First we measure the existing pre-manufactured filters in each unit. In large commercial HVAC units, there is a filter section that holds multiple filters, measure the entire length and width of each filter track in each unit.
Measure existing filter setup
Manufacture custom frames
Next, we take the measurements provided to manufacture custom steel holding frames that will cover the entire length of the filter rack and replace the existing filters in each unit. Each frame features a steel welded wire to offer superior support for high airflow volume.
Select custom filter
Spray Filters Direct offers the best polyester filtration media on the market cut to custom size pads and supplied for the oversized holding frame. Spray Filters Direct offers a variety of lofted polyester filtration media in a variety of lofts and MERV ratings that can be custom tailored to each facilities specific needs.
Eliminate debris bypass
Air always takes the path of least resistance. Gaps or cracks between filters can allow particles to pass through. Our custom oversized filtration system eliminates the bypass between standard size filters. This helps prevent dust and debris from ending up on coils and allows the HVAC unit to continue running efficiently over its life.
Reduce waste
Our custom oversized frames reduces waste by eliminating the cardboard, virgin fibers, glue, and other materials used in constructing pre-manufactured filters. This reduces the waste in our landfills after a filter change. It also allows for a more efficient filer change due to reduced pieces.
Increase particle capture
Increased filtration surface area from maximized area and depth of the filtration surface which helps capture and hold more dirt and dust. Spray Filters Direct polyester filtration media typically has a lower initial resistance and causes a lower pressure drop as the filter is loaded with particles, which reduces strain on the HVAC unit and energy usage.
Save Money. Breathe easier.
Using our Custom Oversized Frame & Pad system reduces labor, filter, maintenance, and energy costs. By reducing unnecessary filter inventory and landfill waste, we help control budgets, improve your HVAC maintenance, and increase your bottom line.
