Our DIF-BN50i is a perfect alternative to the Balston® DFU 9900-05-BK, which is used in the HVAC industry. These filters contain a red dye that bleeds through the element to provide an accurate visual indication that oil is present. The red dye permeates through the element upon oil saturation, making visual monitoring quick and easy. Our product is an equivalent to the Balston® 9900-05-BK DFU since it shares overall dimensions with the Balston® DFU.
