Atlas Copco Automatic Tank Drain Kit, with BV #04A2F5

The Atlas Copco auto tank drain removes condensattion from your tank by using a solenoid valve in combination with an electronic timer.

Pre-selecting the timing and length of each drain cycle minimizes compressed air loss. Compact, easy to install and fully automatic, this accessory is a great upgrade, and is a cost effective solution to keep your tank from rusting out.

Install this electronic auto tank drain and save your hands and knees...out of sight, out of mind!

Extra Details

Condensate follows a serpentine path through a small orifice that is actuated by an electric timer.

The length of time the drain is open and the frequency at which it opens can be adjusted manually by easy to operate dials.

Depending on humidity and duty cycle, requirements for condensate discharge can be set and changed over time.
The “time off” setting determines the interval between cycles from 30 seconds to 45 minutes.
The “time on” setting determines the actual time the compressor drains condensate (.5 seconds to 10 seconds) from the 1/4 in or 1/2 in. condensate outlet port.

The timer’s cycle rate and drain opening time should be adjusted to open just long enough to discharge the condensate.

The timer is properly set when it opens and discharges condensate and then vents air for approximately one second before closing.

Adjustments may be made depending on many factors, including humidity and duty cycle.
To check the “time on” setting to see if it is draining long enough, press the “TEST” button.

The compressor will drain the condensate for the length of time set. Adjust the “time on” setting accordingly.
