Hankison 4460-151-1 Float Drain

The Hankison 4460-151-1 Float Drain is a critical condensate management component engineered for high-efficiency moisture removal in industrial compressed air systems. Built as a direct OEM replacement float assembly, this unit ensures the automatic discharge of water, oil emulsions, and pipe scale without the need for electrical high-voltage wiring. This Hankison 4460-151-1 (also cross-referenced as 4460.151.1, HK-4460-151-1, and HKN4460.151.1) utilizes a level-actuated pilot mechanism designed to maintain system integrity. As a veteran technician knows, automatic float drains are essential for protecting downstream tools and refrigerated air dryers from slugging and moisture carryover. This pneumatic auto drain is rated for heavy-duty service, featuring a robust internal design that resists compressed air contaminants and prevents clogging in high-flow filter housings. By upgrading to the HKN-4460.151.1, contractors can ensure a zero-loss condensate discharge, effectively reducing air-end pressure drops and optimizing the performance of the entire air treatment string.

• Broad Compatibility: Functions as a universal float assembly for various Hankison filter housings and competitive air-line filter models.
• Pneumatic Operation: Operates entirely on system pressure, making it ideal for remote or hazardous locations where electrical power is unavailable.
• Debris Resistance: The internal nitrile seal and specialized float geometry prevent sticking caused by synthetic lubricants or particulate buildup.
• Reduced Maintenance: Replaces manual petcocks with a consistent, level-actuated discharge, mitigating the risk of neglected service intervals.
• Interchangeability: Fully compatible with part numbers 4460.151.1 and HKN4460.151.1 for rapid field replacement.

Is the 4460-151-1 interchangeable with the HKN-4460.151.1?
Yes, the 4460-151-1 is the current production standard and is physically and functionally identical to 4460.151.1 and HKN4460.151.1.

Can this drain be used with synthetic compressor oils?
This Hankison float drain is designed with materials compatible with most standard and synthetic compressor lubricants found in modern rotary screw systems.

Does this unit require a minimum operating pressure?
Like most pneumatic auto drains, it requires a minimum system pressure (typically around 20-30 psi) to ensure the pilot-operated discharge port seats correctly.
