DFAS Return Air Grill, hinged door with removable 1" filter

These decorative while return air grills feature a hinged door which allows the periodic changing of standard 1" filters.  Grills are high x 16" wide which is the size of both bottom and side return air openings on the DFAS cabinet.  When servicing up to 3 blowers only one return air grill is necessary.  However, when 4 or more blowers are used you will need to use two return air grills.  The reason we offer this specific model is that it houses a removable filter which is manditory since not using one would result in the DFAS coil getting coated in dust and grime which reduces the capacity of the coil and the amount of air flow available to all zones.  Made in Canada.
