| Product Name | HAD Series Auto Drain Unit |
| Model Name | HAD (High-efficiency Auto Drain) |
| Function | Automatic drainage of condensate from air filters, regulators, receivers, etc. |
| Drain Type | Float-type automatic drain |
| Port Sizes Available | 1/8", 1/4" BSP/NPT |
The HAD Auto Drain Unit is a compact, highly efficient solution designed to automatically discharge accumulated condensate (moisture, oil, and other contaminants) from compressed air systems. It is most commonly installed on air filters, regulators, dryers, air receivers, and other components in a pneumatic circuit to ensure dry, clean air reaches downstream equipment.
Using a float-operated mechanism, the HAD Auto Drain opens and releases water when the liquid level reaches a predefined point — all without manual intervention. This prevents moisture build-up that could otherwise lead to corrosion, rust, malfunction, or decreased performance in pneumatic tools and actuators.
Built with a durable die-cast aluminum body and a transparent bowl (with optional metal guard), this unit provides both strength and easy visibility for monitoring. Available in 1/8" and 1/4" BSP/NPT port sizes, the HAD Auto Drain is compatible with a wide range of FRL units like the AF, AW, AC Series, and other filter-regulator-lubricator setups.
It is a must-have addition for industrial users who want automated condensate removal, reduced maintenance, and reliable air quality in their systems.
