Item Name Description
1 Purge Valve
The Purge Valve is used to purge air out of a circulating fluid system. It
bypasses the Circulation Valve and is generally used at system startup and
after a fluid change.
2 Circulation Valve The Circulation Valve controls the amount of flow of the circulation loop.
3 Pump
The Diaphragm Pump is an air-operated, reciprocating pump. It is a 1:1
pump, operating up to 100 psi. Air pressure to the pump is directly supplied
from the main air supply of the SL-940E/SL-941E Conformal Coating
System.
4 Fluid Regulator
The Fluid Regulator is an air-piloted regulator controlling the fluid pressure
via the software controlled electro-pneumatic air regulator.
5 Filter Assembly
The Filter Assembly blocks small particles in the conformal coating fluid
from clogging the coating applicator.
6 Fluid Heater The Fluid Heater controls the fluid temperature through the ECXP software.
