ABSTRACT:
An inlet valve and filter arrangement for pneumatic equipment in which a disposable filter and liquid evaporator cartridge is removably received within a cylindrical bore at the equipment inlet. A check valve is constructed normally to prevent passage of air therethrough to the pneumatic equipment, and includes a valve element for engaging the cartridge and thereby opening the valve when the cartridge has been properly inserted into the equipment housing. Thus, passage of air to the equipment for operating the same is permitted only when a filter and evaporator cartridge has been properly inserted therewithin.
