The air flow through a 3 ton condenser for a 2000 hours air conditioning cooling season in Houston TX is 288 Million Cubic Feet.

With a clean coil, 288 Million Cubic Feet of air passes through this 3 ton AC coil per cooling season.

Any more than this and servicemen have to lug either the power washer on roofs or lift the heavy, bulky tanks of CO2 just to clean these coils, only to hope that they will stay clean for the rest of the summer, with dirt and cottonwood only making things worse.

When manufacturers are asked, they always say “They’re cheaper to make them this way,” never considering the serviceman out in the real world.

I hope this will get the attention of engineers to start making their coils higher, wider, or thicker and consider the serviceman out there, instead of only the engineering side.

To say it simply, “If you can’t see through the coils when they are clean, they shouldn’t be built”!

Air Conditioning Contractors

Permatron Prevent Wrap Around Air Filter for the Outdoor Air Conditioner will cut down on the time needed to do each preventative maintenance visit because rinsing this air filter with a garden hose is a lot easier than cleaning the outdoor condenser coil.

Fact - (1/23rd of an inch) 0.042 inches of dirt on an air conditioning coil can reduce it's efficiency by 21%.

Measure unit from the top to bottom for the height.

Measure length of the fin surface area.

The enclosed filter wraps around the outside of the air intake louvers or fins of your air conditioning unit. Make sure your equipment is clean first. Wrap the filter around the unit, aligning the top edge of the filter with the top of the air conditioning unit.

If the Prevent Air Filter is taller than your outdoor unit , excess filter should be folded under at the bottom.

The filter is held in place across the rear of the unit by bungee cords(enclosed). Attach one each at the top, middle, and bottom of the air filter by hooking cord ends directly through the woven filter media. If the filter is longer than the circumference of your unit, excess filter may be folded under at the edges.

Maintenance and Cleaning - Remove the filter from the unit monthly and rinse clean with water. Back flush with a garden hose recommended. Shake off excess water and reinstall filter with bungee hooks. Filter can be sprayed with mild detergent if necessary. Rinse thoroughly.

Millions of dollars and thousands of man hours are spent annually on HVACR system or sensitive equipment downtime, repair and maintenance. Failure to provide effective air intake protection to building or equipment fans, motors, heat exchangers and other process cooling systems adds up to a costly loss of productivity in safe and efficient system operations.

Permatron’s PreVent Equipment Protection Filters are made of permanent, washable polypropylene. A primary prefiltration defense, they help prevent the damage and extensive maintenance that large volumes of debris can cause. Custom sized to fit any air intake, PreVent is UV protected and stands up to extreme outdoor or indoor exposure, corrosive environments, high velocity air flow, as well as industrial cleaning and maintenance handling. Our simple solution to air intake filtration helps reduce operational and maintenance costs over a long useful life.
