Common questions
Who makes GabFilters?
GabFilters are made by Gabtic in its own factory in Giza, Egypt, under an ISO 9001:2015 certified quality system.
Can you make filters in non-standard sizes?
Yes. Send the width, height and depth in millimetres, or a photo of the old filter's label, and we will make it to size in the class you need.
What filter class do most AHUs in Egypt use?
Most commercial air-handling units use a G4 pre-filter followed by an F7 bag filter. Fine-filtration requirements depend on the application and the consultant's specification.
Can GabFilters replace imported filters already installed?
Yes. We match the frame size, depth and efficiency class of the installed filter so it fits the existing housing.
Do you offer filter replacement programmes?
Yes. We survey your units, set a replacement schedule, deliver filters before each change and can replace them on site.
