3.9.3 APA – Air Purge Accessory Description and Dimensions
IRCON’s specially designed air purge is used to help keep the front optics of the Modline 5 clean. The
purge provides a stream of air away from the Sensor to prevent dust and smoke particles from collecting
on the optics.
The APA is positioned in front of the Sensor with the UAA universal adapter or WJA Water Jacket.
Three through holes in the APA accept mounting hardware to assemble accessories together.
The front of the APA has three threaded holes to attach a MFS or MFL mounting flange. Mounting
hardware is supplied with the flanges.
A ¼ inch NPT threaded air inlet is located on the air purge. A flow rate of 3 SCFM (0.09 m3/min.) clean
air is required for most applications. The flow rate can be increased for difficult environments.
Two drain holes provide an outlet for any condensation accumulation. If necessary, these threaded holes
can be plugged with M3 screws.
