Control Devices RH50-0LAAA Condensate Drain 0.5 Inch Npt

Product Description

The Control Devices RH50-0LAAA is a zero air-loss, level-sensing condensate drain designed for compressed air systems. It uses an internal float mechanism to detect actual liquid level and discharge only when condensate is present, eliminating the continuous air loss associated with timer-based drains. The unit accepts a 0.5 inch NPT inlet and handles system pressures from 40 to 170 psi. It is installed by compressed air system technicians and industrial maintenance professionals in applications where air loss from automatic drains represents a measurable efficiency cost.

This condensate drain is suited for use on air compressors, air receivers, filters, dryers, and other compressed air system components where moisture must be removed automatically without venting pressurized air. The Rust Handler designation indicates corrosion-resistant construction appropriate for environments where condensate acidity or humidity accelerates wear on standard drain hardware. It is used in both light industrial and commercial compressed air installations.

Key Features

• Zero air-loss operation — discharges condensate only when liquid is detected, not on a timed cycle
• Level-sensing float mechanism provides demand-based drainage
• Operating pressure range of 40 to 170 psi suits a wide range of compressor systems
• 0.5 inch NPT inlet and outlet connections for standard pipe integration
• Corrosion-resistant Rust Handler construction for extended service life in humid or acidic condensate environments

Compatibility

Designed as an OEM-style replacement or new-installation condensate drain for compressed air receivers, filters, aftercoolers, and dryers with 0.5 inch NPT drain ports operating between 40 and 170 psi.

Installation Notes

Installation should be performed by a qualified compressed air system technician or industrial pipefitter. Depressurize and isolate the system completely before removing any existing drain hardware or making connections. Use appropriate thread sealant on NPT fittings and verify all connections are leak-free before returning the system to pressure. Ensure the unit is mounted in the orientation specified by the manufacturer to allow the float mechanism to function correctly.
