• CGG – equipped with a filter with gel gasket and 1 tube for measuring pressure drop or for aerosol concentration test
• CGO – without a filter and measuring tubes

The casing is welded, with wall thickness of 1.5 mm painted in RAL 9010. There are available 4 casing sizes [mm]:

• 318 x 318, for filter size 305/305/78-90 mm, duct connection: round 160 mm / rectangular 200 x 100 mm (vertical or horizontal)
• 470 x 470, for filter size 457/457/78-90 mm, duct connection: round 200 mm / rectangular 335 x 100 mm (vertical or horizontal)

• shut-off flap is made of sheet steel, integrated in the duct connection fittings, enables a filter replacement without stopping the air handling unit
• without shut off-flap

The outlets (face panels) in RAL 9010 are attached to the filtration unit body via four screws situated in the corners (except ADQ type). The outlets are available in 5 versions of design:

• A/C/D – Twisting airflow outlet with fixed air routing elements (A – diffused/whirl flow, C – direct flow in two directions, D – direct flow in one direction)
• ADQ – Discharge on four sides
• S – Twisting airflow outlet with adjustable air routing elements
• D22/D40 – Perforated steel plate (D22 – with 22% free surface area, D40 – with 40% free surface area)
• NOZ – With adjustable air nozzles

There are available following installation options:

• in LS light ceiling (clip-in) – casing in basic version, LS-cassette with an opening to be riveted on site.
• in KS, KSH cassette ceiling – casing with peripheral L-ledges (to be riveted on-site). Unit installation onto the grid from above.
