Positive displacement blowers have intake filters to protect the close tolerance lobes inside the blower. Compressor filters are also of critical importance to the life of the unit. The dirt’s in this type of unit are atmospheric and usually very fine. When we receive a compressor or intake filter the dust and dirt look nothing like the dirt on a canister filter.
FilterPro has a proven process to clean these expensive filters. The most durable filters in these systems are wire wrapped polyester. A thin gage screen wire is pleated with the polyester media creating a strong support which follows the contour of the pleats.
Even more important than the cleaning process is the inspection of an intake filter. Any small holes in the media may allow particles through the filter and can cause a very expensive piece of equipment to fail. Variations on the old “candle testing” method are still used today to inspect an intake or compressor filter. Other tests may include smoke testing for holes, or a die testing.
IS this a new filter or a cleaned filter?
The biggest intake filter FilterPro has cleaned is almost 3 feet in diameter, and two feet high. This filter is sent in once a year by a food ingredient company for FilterPro to clean, and recondition. We have cleaned the same filter for the last three years in a row.
An idea developed by FilterPro almost ten years ago is the Pro-Wrap™. The idea was developed at a motorcycle race. It was noticed that between races the riders would change an outer wrap on the carburetor filter instead of changing the entire filer. From there the Pro –Wrap™ developed. Pro-Wrap™ is a polyester material with a dry tactifier applied to the outside of the media. The media has a very low differential pressure and will not affect the breathability of the filter. The filter Pro-Wrap™ is constructed with surged edges for durability. The pre filter manufactured with Velcro tabs sewn into the end of the filter for ease of installation and removal. Thus, the operator does not have to remove the filter or shut down the unit. Simply pull off the old Pro-Wrap at the Velcro strip and install the new one. The dirty Pro-Wrap can be washed off with a hose and re-used several times.
The Pro –Wrap™ has been widely accepted and used throughout industry where the intake or compressors are located in dusty environments.
Greatly extend the life of your expensive intake or compressor filter.
Don’t change your filter all the time change your Pro-Wrap™
