WLD1500 Inverted Bucket Liquid Drainers

The WLD1500 Series Inverted Bucket Liquid Drain Traps are recommended for the removal of liquids from compressed air systems. A scrubber wire is used to keep bleed hole on top of inverted bucket from clogging due to oil that may be present in the water being drained. Oil mixed with water is typically found on compressed air systems.

Hardened stainless steel valves and seat
Only two moving parts
Scrubber wire in air vent of bucket
Discharge orifice at top of trap reduces potential for clogging
In-line repairable

Description

WLD1500 Inverted Bucket Liquid Drainers are recommended for the removal of liquids from compressed air systems.

Determine the capacity (lbs/hr) required at the specified differential pressure. Locate differential pressure on capacity chart; move down column to capacity required. Make sure to select the correct model based on the maximum inlet pressure.

Capacity in lbs/hr is based on differential pressure across the drainer. Select a model with an equal or higher PMO (max. operating pressure) than the maximum inlet pressure to the drainer. If the pressure to the drainer exceeds the PMO, the drainer may not open. If discharging to atmosphere, the differential pressure is equal to the inlet pressure.

Example:
Required to drain 200 lbs/hr at a differential pressure of 5 PSI. The maximum inlet pressure is 30 PSIG.

Select Model:
WLD1521-13-N, 3/4” NPT, with strainer, capacity up to 220 lbs/hr based on 5 PSI differential pressure.
