Compatibility Guide
Don't Know Your Model Number?
You don't need one. Our interface-first matching system lets you find the right replacement part by measuring what matters — connection type, key dimensions, and electrical specs. No model number, no serial lookup, no guesswork.
Why Interface Matching Works Better
Traditional replacement requires a model number, but evaporative coolers often have missing labels, multiple OEM variants, or obsolete series. We match by the physical and electrical characteristics of the part itself — the parameters that actually determine whether a replacement fits and functions.
Measurable
You can measure thread size, shaft diameter, or pad dimensions with basic tools. No special equipment needed.
Universal
Interface types are standard across manufacturers. A 1/2" threaded pump connection is the same regardless of brand.
Reliable
If the interface, dimensions, and specs match, the part will work — regardless of what model it was originally made for.
Four Ways to Match Your Part
Choose the method that matches the information you have. Combine approaches for the most confident match.
By Interface
Threaded, flanged, push-fit, hose barb, or clamp mount. The connection point is the most reliable matching parameter.
Browse threaded, push-fit & moreBy Dimensions
Shaft diameter, pad size, bolt pattern, frame dimensions. Physical fit is determined by key measurements.
Browse 12mm shaft, 600mm padsBy Electrical
Voltage, power (W), RPM. Electrical components must match operating parameters for safe, correct function.
Browse 110V, 220V, RPM rangesCross-Reference
Find alternatives by part function — pump, seal, motor, capacitor. Follow the replacement chain.

Step-by-Step: How to Identify Your Part
A systematic approach. Complete these steps and you'll have everything needed to find the right replacement.
Determine the System
Which part of the cooler? Water system, evaporation, air movement, electrical, structure, or maintenance.
Check the Interface
How does it connect? Threaded, flanged, push-fit, or clamped. Measure thread diameter or bolt pattern.
Measure Key Dimensions
Shaft diameter, pad size, bolt hole spacing. Use calipers or a ruler — millimeters are best.
Note Electrical Specs
Voltage, power (W), RPM. Check the label on your existing motor or pump for these values.
