RTi ED-2-4 Electronic Timer Tank Drain – Automatic Compressor Condensate Drain

Never forget to drain the tank again — and never send a slug of water down your air lines.

One of the most critical items in any air system is often overlooked: a reliable drain on the main reservoir tank. The ED-2-4 automatically drains your tank as often as needed to provide water-free air downstream. Use it on any air reservoir tank, air/water separator, air filter, air dryer or drip leg wherever condensed water removal is necessary.
