The SMART-GUARD zero air loss condensate drain provides effective and efficient condensate removal while saving you time and money.
With innovative features like a remote alarm contact, a test button, LED indicator lights and an optional heater for cold weather applications, the SMART-GUARD is the optimum choice for reliable, energy saving condensate removal.
A robust 2/2-way capacitive level sensor operates a direct acting valve to discharge condensate without losing any valuable compressed air. An integrated mesh strainer protects the valve from blockage and alarm contacts provide remote, real time indication of drain function.
For quick and easy installation and maintenance, all models include a six foot power cord and feature a removable electronic module and top cover, allowing you to disassemble the drain without disconnecting any pipe work.
The SMART-GUARD meets the demand of virtually any application, covering all compressed air systems up to 3500 CFM.
The 115VAC version of this drain is supplied with a 6 ft. power cord with plug and the 230VAC version is supplied with a 7 ft. power cord.
Robust aluminium housing with three inlet options, offering you installation flexibility.
Integrated mesh strainer, offering you valve orifice protection.
Extremely easy to disassemble, offering dissasembly simplicity and time saving during routine maintenance.
