HEYLO PF1400 PowerFilter Air Filter

General aspects

ATTENTION: Read carefully before starting up ! Please observe the notes in the operating instructions carefully. In case of non-observation, the warranty claims will become void. The manufacturer shall not be liable for any damage and/or consequential damage resulting.

PF 1400 is a mobile air filtration unit. The air drawn from the environment and is passed through a two-stage filtration system. In the process the filter collect particles from the air, such as coarse and fine dusts, mould spores, pollen, pet hair and smoke. Apart from circulating air operation, vacuum for refurbishment areas can be produced by connecting air hoses. In addition, the filtered air can be removed and/or added on the suction side and exhaust side by connection of hoses.
In order to produce “clean air”, the air flow and filtration are perfectly harmonised to each other by PF 1400. The motor directs the air through two different filter stages: a pre-filter and a main filter. The first filter stage (pre-filter) separates coarse dusts of up to 3 µm. The second filter stage (main filter) separates micro-dusts and suspended matter up to 1 µm. On account of the filter class used HEPA-H14 in conformity with German standard DIN EN 1822 or of dust class H in conformity with German standard DIN EN 60335, the filtration unit is suitable for the filtration of certain biological agents, such as mould spore and other contaminants. The number of required air exchanges depends on the type of noxious substance. Corresponding official and/or professional association regulations have to be observed. The operator of the unit shall be obligated to obtain information on handling hazardous materials. Potentially, the operator has to prepare a risk assessment prior to refurbishment work.

Putting into operation / operation

1. Switching the unit on : To switch the unit on, the main switch (A) has to be turned to the right (then the switch is lit yellow).

2. Power control : The power regulator (B) can be set to an air flow rate of between 0 and 100 per cent. It is recommended to operate the unit at 100 per cent.
   ATTENTION : After switching the unit on, it will take about 10 s to start up the fan motor. This is no fault !

3. Change of filter indicator: When the main filter is saturated, this will be indicated by display (C). When this signal is released, the main filter as well as the pre-filter has to be replaced. Please remember to have sufficient filter material available.
   The service life of the filter depends on the quantity of dust drawn in. An integrated differential pressure switch is used to determine the air flow through the filter.

4. Energy metre : The energy metre (D) can be used to read off the power consumption in kW/h, which, if and when necessary, is included in the documentation or used for billing with the insurances.

Application / fields of operation

The main purpose of PF 1400 is the use in case of dust-intensive work at varying work locations. Here the unit is used for industrial safety and health protection, ensures the refurbishment targets and increases the efficiency of work. By air filtration, harmless ambient air is ensured. This is used for the protection of the employee, and at the same time increases the work performance. Unaffected areas and residents are protected against detrimental particles from spreading. By sealing off and by generating negative pressure in the refurbishment area, the success of micro-cleaning in the removal of contaminants is considerably increased.

ATTENTION: Like all low pressure units, PF 1400 must be operated only with the corresponding expertise when dealing with contaminants. The local trade association will inform you about the required proof of expertise.

ATTENTION: PF 1400 must not be used in explosive areas.

Design: If PF 1400 is used in areas, in which people are employed, the professional association of the building industry (BG-Bau in Germany) requires a 15-fold air exchange. In order to ensure maximum performance of PF 1400 and to achieve a correct display of the filters used, the air purifier has to be operated at maximum fan stage. If suction or exhaust hoses are used, all hose connections have to be fitted with hoses (exhaust air two hoses of 205 mm each – accessories see chapter (11)).

Circulating air operation: The PF 1400 must be set up in the middle of the area concerned. The suspended matter stirred up during work and/or use of the room is collected by the continuous air exchange of the unit and is found in the filter. In this case an air hose should be placed on the air outlet side or on the suction side in such a way that a ventilation is ensured by the entire area.

Collection at the source Particles should be collected as close as possible to the point of origin. Basically, quick-running tools should be fitted with dust extraction by means of safety vacuum cleaner. In order to collect additional free dust, the PF 1400 can be provided with air hoses. These should be placed as close as possible to the source. This minimises the spread of dust in the room air (optionally a holder is offered as an accessory).

Negative pressurisation: The refurbishment area has to be sealed off from the non-affected areas. This is done by dust protection wall or film doors. The working area should be kept as small as possible. Hoses are used to pass the filtered exhaust air from the refurbishment area into the open. PF 1400 can be set up in the refurbishment area as well as in front of the refurbishment area. Let PF 1400 run with low pressure for the duration of the work without interruption.

WARNING – breathing risk : When operating PF 1400 in a closed area, all power sources to open fires, such as chimneys, boilers, oven, water heaters and air conditioning units, have to be switched off in order to reduce the risk of the return of deadly carbon monoxide.

When the change of filter indicator lights up during operation, the pre-filter or the main filter has to be replaced immediately. More information is rendered in the chapters titled “Filter exchange” and “Maintenance”.

Laying of hoses: The connecting hose of PF 1400 or rather of the entire unit itself has to be laid as close as possible to the source of the air contamination. With increasing distance of the suction hose from the origin of the air contamination, the share of air contamination decreases disproportionately. For improved acquisition at the point of origin HEYLO provides a base stand to hose connection socket on the suction side. In order to place the hose ends at a higher position, the hoses can be attached to telescope rods using lashing straps. Ensure move of the suction hoses in the work area as close to time as possible. Hoses should be laid without kinks, if possible, and in a straight line to the air purifier. If and when necessary, auxiliary constructions have to be set up for overcoming differences in height, for example (by chamfering of supporting wood nailers, for example). In the area of the suction hoses, the constriction of the cross-section by kinks increases the suction air flow.

In the exhaust air hose, the exhaust air flow counter the cross-sectional constriction by kinks. The suction hose has to be arranged in such a way that contaminated air is removed from the breathing area of the employees, and fresh air and/or purified air is supplied to the employees.  The purified exhaust air of the air purifier has to be passed to well ventilated areas and/or to the outside. A return of purified air into the working area is permitted only, if sufficient base ventilations with fresh air is ensured at the same time. A second air purifier may be set up for air ventilation, if and when necessary. Please observe the national health and safety regulations.

Required air exchange : The required air exchange depends on the type and volume of air pollutants. Correspondingly, air exchange rates of between triple and 20-fold of the room volume may be required. The professional associations recommend a 15-fold air exchange. In case of quartziferous A dusts, the occupational exposure limit value is 1.5 mg/cum, and in case of E dusts 10 mg/cum (TRGS 900).

Example:
A 15-fold air exchange is required for a room volume of 40 cum. The required air volume is 15 x 40 cum, thus at least 600 cum/h. When the filter display has been activated, HEYLO PF 1400 continues to have an output of approx. 600 cum/h. A sufficient air exchange is thus ensured.

The precise requirements are listed in the installation guidelines mentioned in chapter (8).

Filter / change of filter

Filter system : The PowerFilter PF 1400 uses a two-stage filter system which uses the latest HEPA filter technique. The first filter stage consists of one or two pre-filters, and the main filter stage of a robust HEYLO pleated filter in various filter classes.

Change of filter: ATTENTION : Basically, the filter shall be changed in the black area. Alternatively, the said can be carried out outside as well
(The area loaded with dust is referred to as black area; the white area is the adjacent “clean” area).
Independent of the change of filter indicator, both filters have to be replaced after every use involving contaminants. If the composition of the particles drawn in is not known, the filter should be replaced completely after use on the respective building site. Both filters have to be replaced so that the soiling (contamination) is not passed into clean areas.

Service life of filter: The service life of the filter depends on the quantity of dust drawn in. Very fine dust may drastically reduce the service life. Saturated filters have to be replaced.

Change of filter indicator: When the signal is triggered, the pre-filter and, if and when required, the main filter have to be replaced.

ATTENTION: Before changing the filter, put the unit out of service ! Please refer to the following table to determine which filter class is required for which material:

Change of filter

Pre-filter : The first filter stage consists of one Z line pre-filters. The pre-filter(s) is/are pushed into the filter cassette. In order to replace the pre-filter, the two clamp fasteners of the filter cassette have to be opened. Now the filter cassette can be removed from the front and the new pre- filter can be pushed in. Subsequently place the filter cassette in the unit again.

Main filter : To replace the filter, undo the quick-release fasteners of the pre-filter cassette, and remove the pre-filter cassette. Then take out the main filter panel, and place the main filter.

Disposal : If the unit has been used in polluted air, pack the used filter in air-tight sacks and dispose of them professionally. Wear personal safety equipment, especially suitable breathing protection, to change the filter.

1. Open the side closures.
2. Remove the pre-filter cassette.
3. Remove the pre-filter holder.
4. Place the main filter.
5. Place the pre-filter holder.
6. Place the pre-filter.
7. Place the pre-filter cassette.
8. Close the connections.

When using hoses, an optional front grille with hose connection nozzle as well as hose connection nozzle for the blow-out hose shall be used.

Connection of the suction hose:

1. Replace the pre-filter cassette.
2. Connect the hose.

Connection of the blow-out hose:

1. Mount hose connection nozzle.
2. Connect the hose.

After use
After every use PF 1400 has to be cleaned thoroughly before taking it out of the refurbishment area. This is done by using a safety vacuum cleaner and by moist wiping. Compressed air is not permitted here. The area around the air intake has to be cleaned especially thoroughly. For transport from a contaminated area, the unit can be closed with a sealing cover so that the contamination cannot be passed only (see optional equipment).

Attention: Let the unit dry before fitting a new filter !

Protective measures during change of location : If the location of the unit is changed, the pre-filters should be exchanged prior to transport. If necessary, separate transport in an air-tight transport container or an air- tight garbage bag may be sensible.
