Pro-source AD-01 Automatic Drop Leg Drain

Product Description

The PRO-SOURCE AD-01 is an automatic drop leg drain designed for use with compact compressed air filters. It automatically expels collected moisture and contaminants from the filter bowl without manual intervention, helping maintain consistent air quality in pneumatic systems. At approximately 1.98 inches high and 1.02 inches wide, the AD-01 is a compact accessory suited for installations where space is limited. It is typically installed by industrial maintenance technicians or compressed air system specialists maintaining pneumatic line equipment.

The AD-01 is intended for use as a direct accessory on compatible compact compressed air filter assemblies. It is well suited to light industrial and commercial pneumatic applications where moisture buildup in air lines must be managed reliably. The automatic drain function reduces the maintenance burden of manual bowl drainage, making it appropriate for installations where service intervals are extended or where access to the filter is inconvenient.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system service. Before installing or removing the drain, depressurize the air line completely and verify zero pressure at the filter assembly. Follow applicable industry codes and the filter manufacturer guidelines for accessory attachment torque and sealing. Do not pressurize the system until the drain is fully seated and all connections are verified leak-free.
