Port-A-Cool Pressure Regulator Replacement

This Port-A-Cool pressure regulator is a direct replacement component designed for specific evaporative cooling units. It restores proper pressure control when the original regulator fails or drifts out of calibration. Maintenance technicians and facility managers handling compatible Port-A-Cool models will use this part to return the cooler to specification.

Includes Pressure Regulator Only

The package contains the regulator unit itself with no additional fittings, tubing, gauges or mounting hardware. Installers must reuse existing connections and seals from the removed assembly. No software, calibration tools or documentation beyond the basic identification label are bundled with this replacement item.

Direct Swap on Compatible Units

Installation is a straightforward remove-and-replace procedure on the listed Grainger item numbers 1PX57, 2AAG7, 4HA13, 4HA14, 4HA16, 4HWH9, 4HWJ9, 4WT31, 4WT32 and 5YMJ3. Common issues arise when the regulator is fitted to unlisted models or when worn supply lines leak after re-assembly. Buyers needing a regulator for other cooler brands or higher-pressure systems cannot use this part.

Questions about this item

Does the regulator itself need periodic replacement, or is it a permanent part of the cooler?

The regulator is sold as a replacement component, so it is expected to wear out and be swapped when pressure control drifts.

What is the first sign the regulator is reaching its limit during long shifts?

Output pressure will start to wander from the set point, causing the cooler’s airflow to become inconsistent.

How much extra heat or noise does the regulator add when the unit runs all day?

The regulator is a passive mechanical part; it adds no electrical load, no fan noise and no measurable heat of its own.
