Mechanically operated 'zero-loss' drains

economy . . . choice . . . stock

Usually referred to as ‘float drains’, these devices have two great advantages: they respond to the presence of condensate and so, in theory they waste no compressed air; and they require no power supply, making them ideal for large and widely distributed sites.

There’s a wide range of designs available from the very basic, to those with sight glasses, alarm indications, and external functions designed to allow an engineer to ‘exercise’ the mechanism on maintenance rounds to help prevent sticking.

STERLING stocks several types from high capacity as shown, down to the very small units usually supplied inside compressed air filters and water separator housings.
