Hankison 506 Auto Drain

The Hankison 506 Auto Drain is a heavy-duty, pneumatically operated condensate management solution designed for seamless integration into high-capacity compressed air systems. Engineering as a direct drop-in for the HKN-506, this Trip-L-Trap series unit features a top connection configuration with a 3/4 inch NPT inlet and a 1/4 inch NPT outlet. It is built to handle maximum operating pressures up to 300 psig and offers an impressive discharge capacity of 24 gallons per hour. Unlike standard electric drains, the 506 utilizes a stainless steel float and a resilient pilot valve seat to ensure zero-loss operation, meaning no valuable compressed air is wasted during the cycle. Its internal stainless steel mechanisms are specifically designed to remain impervious to aggressive synthetic lubricants, while the integrated skim tube ensures that separated oil is removed first to prevent downstream contamination. This pneumatice condensate drain is an essential component for contractors maintaining large-scale moisture separators and receivers.

• Zero-Loss Efficiency: Operates strictly on demand using a float-activated pilot valve, preventing the loss of compressed air and reducing system energy costs.
• Synthetic Lubricant Compatibility: The stainless steel internal mechanism is resistant to the chemical breakdown often caused by synthetic compressor oils.
• High-Pressure Reliability: Rated for severe duty with a 300 psi maximum working pressure and a wide temperature range of 35°F to 280°F.
• Simplistic Maintenance: Designed for easy field servicing; use the 05.7501-03 rebuild kit for annual maintenance to ensure long-term mechanical integrity.

Does this drain require an electrical hookup?
No, the Hankison 506 is fully pneumatic and operates using the system's own air pressure, making it ideal for remote locations or hazardous areas where electricity is unavailable or restricted.

How does it handle oil-laden condensate?
The unit features a specialized skim tube. This design ensures that oil, which floats to the top of the condensate, is discharged during every cycle, preventing oil buildup inside the trap.

Can I use this as a replacement for the older HKN-506?
Yes, this model is the direct technical replacement for the HKN-506, sharing the same 3/4" NPT top inlet footprint for straightforward installation.
