This condenser pad will fit all of the GWIN Condensers available.
Why purchase an Condenser Pad?
1. Protects the unit from pest, insects and critters that may cause damage to the condenser.
2. Reduce vibration from the AC against this pad so it does not hit against the ground. If a condenser is not placed on a support system like a pad, you risk damage being done each time the condenser vibrates against the ground.
Pros
- Unaffected by UV or weather
- Uniform rubbing transfers load evenly
- Lightweight, yet incredibly rugged
