Description
Systemair SPM iris damper with more choking ability.
Function
The SPM is an iris damper for measuring and adjusting the air flow, with more
choking ability than the SPI. The SPM has the following specifications: low
noise level, centricallyformed air flow and fixed test points for precise
measurements.
Accessorie, Access door RLL, is recommended for use with SPM. Available in
sizes ø 160-400, but not for size 300.
Design
The damper is manufactured from galvanised sheet steel and is fitted with an
airtight rubber seal. Size ø 160-400. How to use for exhaust air This device
can be used for xhaust air.
Mounting
The SPM adjustment damper must be installed in accordance with the distances
required to minimise air-flow deviation. Reducing or enlarging the duct to the
next duct size does not require any specified distances for minimising
deviation. The SPM enables the taking of precise air-flow measurements at all
points including points close to duct deviations such as T junctions and
bends, and points in front of other supply-air devices.
