Hankison 3152270 Auto Drain

The Hankison 3152270 Auto Drain is a heavy-duty internal float drain designed to replace the legacy 05-4170-08 model. This pneumatic condensate drain is essential for maintaining dry, contaminant-free air in compressed air systems, specifically within Hankison HF series inline filters and refrigerated dryers. Engineering specs include a 9/16-inch straight thread connection ("large thread" style) and a maximum operating pressure of 250 PSI. Built with a robust corrosion-resistant body, it features an internal screen to prevent debris from clogging the valve mechanism, ensuring a tight seal once the liquid is discharged. For contractors, this is the standard OEM solution for Champion air compressors and Kaeser dryers that utilize Hankison filtration components. The normally closed design improves energy efficiency by preventing the loss of valuable compressed air during the moisture evacuation cycle.

• Universal System Compatibility: Direct drop-in replacement for 05-4170-08 across brands like FS Curtis, Deltech, and Champion.
• Industrial Performance: Rated for high-pressure environments up to 250 PSIG and temperatures from 33?F to 140?F.
• Automatic Operation: Features a buoyancy-driven float that discharges condensate without the need for electrical power or manual intervention.
• Maintenance Efficiency: Integrated internal screen captures particulate matter, protecting the automatic drain valve from premature wear and sticking.

Common Questions

Is the 3152270 compatible with 05-4170-08 installations?
Yes, the 3152270 is the updated manufacturer catalog number for the 05-4170-08. It matches the same 9/16" thread pattern and footprint, making it a direct replacement for compressed air filters and dryer housings.

What causes a float drain like the 3152270 to get stuck open?
Debris or heavy oil sludge typically causes internal float drains to stick. While this unit includes a debris screen, technicians should perform a daily manual drain check by turning the knurled fitting to verify the discharge path is clear.

Does this unit Require an external power source?
No, this is a pneumatic automatic drain. It operates entirely on the mechanical buoyancy of the internal float, meaning no wiring or solenoid power is required for the condensate management process.
