Introduction

1.1 Gamma GTH3 RFA
Gamma GTH3 RFA is meant for industrial use such as metal or wood grinding or painting. This product is not designed to use in welding applications. The Gamma GTH3 RFA model is designed to be used together with PFU 210e powered filter unit or RSA 230 air supply regulator for the user’s respiratory system protection.
Gamma GTH3 RFA offers the highest level of respiratory protection: TH3 classification (max inward leakage 0,2%) with PFU 210e, and 3B (max inward leakage 0,5%) with
RSA 230 and eye protection against high speed (120m/s) particles.
(For operating PFU 210e or RSA 230, refer to the instructions delivered with the equipment in question in conjunction with this manual.)

Safety

**Warning:**

• It is strictly forbidden to use any other than Kemp-pi branded filters or other parts or accessories with Kemppi’s personal protection equipment. If you do not respect this safety regulation, serious damage to your health may occur.

**Warning:**

• We recommend a usage period of 5 years. The period of use depends on various factors such as use, cleaning, storage, and maintenance. Inspect the helmet before each use. Replace damaged or worn parts.
• Use all adjustment features for maximum protection.

Warning:

• Materials that may come into contact with the wearer’s skin may cause allergic reactions to susceptible individuals.
• Only operate this product within the temperature range -5…+55 °C.
• The product is not intended for use in environments with a risk of explosion.
• The helmet does not protect against explosive devices or corrosive liquids.
• The helmet is not suitable for laser welding and oxyacetylene welding/cutting processes.
• Set and tighten the face seal properly. If the face seal is not tight, the respiratory protection may not reach the best level.
• When the helmet is worn over any spectacles, they may transmit the impact of high-speed particles, thus creating a hazard to the wearer.
• If protection against high-speed particles at extremes of temperature is required then the selected eye protector should be marked with the letter T immediately after the impact letter, i.e. FT, BT or AT. If the impact letter is not followed by the letter T then the eye protector shall only be used against high-speed particles at room temperature.
• Never use a scratched or damaged welding filter and ocular.
• If the symbols of the marking are not common to different parts of the protection equipment, the lower protection level shall be assigned to the complete protective equipment.
  **Note:** This product protects against high-speed particles only at normal room temperature – Designation B (120m/s) is common for ocular and frame.
