Sensor Aspirator Units - Type 1 & 2

Operational

These sensor aspirator units (Type 1 and Type 2) from Frontline Safety consist of a pump and flow monitor and a tough enclosure. The pump and flow monitor will continuously monitor with the pump motor having a shelf life of up to 6 years. If you require room to accommodate an on board sensor/transmitter and a larger pump then a deeper box is required. This comes in the form of the Type 2 Sensor Aspirator Unit.

Additional Information

The ASU 1 & 2 can be mounted at chest height for easy access and viewing with the sample line able to travel to a high or low target area. The enclosure is made from ABS which is a robust flame retardant material and is suitable for safe area use only.
