Dwyer Explosion Proof Air Flow Switch

Screw type on top of housing.

Dwyer explosion proof air flow switch.

Series 1950 set points from 03 to 20 in w c explosion proof and weatherproof. Explosion proof differential pressure switch combines the best features of the popular pressure switch with the benefit of natural gas compatibility. The mcdonnell miller afe 1 series explosion proof air flow switch is used to prove flow in ducts in hazardous areas. The switches control dampers according to flow and shuts down burners when air flow through heating coil fails.

This category contains sensors with an electrical contact output at a specific air flow rate. The 1950g is very compact about half the weight and bulk of equivalent conventional explosion proof switches. Easy access to the spdt relay and power supply terminals is provided by removing the top plate of the aluminum housing. Dwyer pressure switches are explosion proof atex approved weatherproof compact and low cost.

Air and non combustible compatible gases. Air quality air flow switches. Dwyer s flow products included in this category are compact and explosion proof. They monitor liquid gas and air flows.

Some applications are control dampers according to flow signals alarm shuts down burner and protects pumps motors and other equipment against low or no flow. Series v8 field adjustable 1 to 6 inch pipe leak proof body chemical resistance. A supply voltage of 24 vdc 120 or 240 vac is required. Temperature range 40 to 140 f 40.

Applications include hvac applications process applications all weather applications and gas furnaces. Compact and easy access to the spdt relay. Series 1620 high reliability repetitive accuracy within 1. Applications include proof of boiler flow air conditioning controlling of dampers according to flow and protecting pumps motors and other equipment against low or no flow.

Monitor flow in 1 2 to 2 12 70 to 50 80 mm pipe explosion proof compact flotect mini size flow switches are compact and designed to monitor liquid gas or air flows. Applications include low air flow condition duct alarm fan monitoring damper feedback air handlers and air flow proving in hvac systems.
