Qualities

Filters Direct holding frames make the correct installation of a filter a simple task. The standard clips provided facilitate the swift and leak-tight installation of filters in frames. All bag-filter holding frames comprise an endless spray-on gasket, which renders leakage literally impossible, provided the frame is installed correctly. The special pre-drilled holes make it a simple task to fit the frames. In the event that a large filter wall is to be constructed, it is advisable to fit additional reinforcing. In addition to the standard 2” model, there is a 3” model available, which facilitates the installation of a 2” pre-filter and a 1” bag filter in a single frame. This solution is particularly useful in air treatment cabinets which are rather cramped, but nevertheless required the upgrade to an additional filter.
Filters Direct has devised a number of innovative solutions for the swift and convenient installation of filters in its HEPA holding frames. As leak-tightness is a crucial requirement in the case of a HEPA filter frame, star nuts can be fitted to ensure a tight fit between the filter and the gasket.

Advantages

• Easy fitting using clips
• Endless gasket
• Option of fitting several filters in a single frame
• Robust frame
• Swift fitting of frames, thanks to pre-drilled holes

Construction

The holding frames are made of stainless steel. An epoxy coating can also be applied to frames on request. High quality steel is used in manufacturing the frames, to ensure ample rigidity. Furthermore, the construction design pays consideration to optimum frame stability and ease of installation.

Application

These holding frames are widely used in air treatment cabinets and air inlet systems for equipment such as gas turbines. The frames have standard dimensions and are a good replacement for the used holding frames removed during the renovation of air treatment cabinets.

Installation

•    In the event that several frames are to be fitted next to one another, it is advisable to also fit additional reinforcing
•    Once the frames are fitted, sealant should be applied around
•    The edges to prevent any leakage
•    The frames should be correctly installed; the clips should be fitted on the dirty air side.
