HIGH EFFICIENCY MEDIA CAPTURES MORE FINE PARTICULATE
A MERV 11 rating requires a 65% to 80% efficiency on 1 - 3 micron particles and greater than 85% efficiency on 3 -10 micron particles, when tested in accordance with ASHRAE Test Standard 52.2. AmAir 1100 meets and exceeds these requirements.
CONSTRUCTION AND PERFORMANCE
The AmAir 1100 also has a heavy duty,
expanded metal pleat support grid laminated to the media pack to increase rigidity and
help maintain proper spacing between pleats. Proper pleat spacing ensures maximum
efficiency, low resistance, and high dust holding capacity.
To support the increased pleat depth of the
4" AmAir 1100, a pleat stabilizer is added to maintain proper spacing and improve
dust holding, resulting in longer service life.
Media Pack Support Retainers - metal bottle cap retainer is used on custom made filters instead of a beverage board retainer.
1" Thick Filters:
2" and 4" Thick Filters
Only the width and length can be custom made. Filter depths cannot be custom made and are stated according to nominal industry standards. Actual filter depths are as follows:
In general, all standard filter sizes are stated according to their nominal size and not their actual size. This information can be found on the side of your filter. For example, our standard AmAir 1100 (nominal) 20x20x1 measures (actual) 19-3/8 x 19-3/8 x 7/8. The nominal size represents the size of your filter rack. The actual size represents the size your filter needs to be to fit inside your filter rack. If your filter rack is an odd size, a standard sized filter may not fit properly. In this case, you would need to order a custom made filter.
When ordering custom made filters please
note that these filters will be made to your exact specifications ± 1/8 inch.
Therefore, please provide us with the exact width and length of the filter you are
needing. Please be sure to measure exactly for a snug fit to allow the filter to fit
within the rack but without air seepage around the filter.
Minimum filter size: 4" x 4" and a Maximum filter size: 25" x 35". We can build filters larger then 25" x 35" but they are considered a double size (please call us for pricing at 1-888-844-5820). If a double sized filter is required, you may consider putting two filters together to achieve the size desired, i.e. 18" x 40" you would need two 18" x 20" air filters.
