Complete and space-saving ”Plug & Play” compressed-air cleaned filter unit with integrated fan to be used for air filtration from processes that form limited dust volumes (welding, cutting, grinding and similar).

Can be placed in the production room and filters extraction from up to 7 simultaneous welding places.

CFL: Air volume: Up to 8,200m³/hVacuum: Up to 5,000PaFilter area: 26 - 168m²

Description filter unit• Polluted air is led in through the lowest connection on unit side,

wherein preseparator is integrated. • Airisfilteredthroughvertical-placedfiltercartridgewithinternalfilter

core, which optimizes cleaning effect.• Differentialpressurecontrolledcleaningoffiltercartridgesthrough

integrated compressed-air system incl. automatic after-cleaning for optimized regeneration of filter cartridges.

• Cleanairisledoutthroughconnectioninunitside.• Dust is collected in dust container in unit bottom. Dust container

mounted in Gram Quicklock-adjustable dust container suspension.

Description fanUnit is above equipped with a fan type VAE or RAV, 3x400 VAC, 50 Hz, 2800 rpm. Both fans are equipped with closed fan wheel with backward-curved straight self-cleaning blades, static/dynamic balanced according to ISO 14694 (BV3 G 6.3). Fan delivers air in fan enclosure, where air noise is dampen by sound absorbing material, before it is led out through bolted-on connection.

Simple mounting, connection and operationUnit delivered ready for use. Equipped with fork pockets and crane lifting points for easy transport and installation. Integrated motor starter and CEE-plug on front make connection quick and easy. Unit is also available for opera-tion with external frequency converter. In that case motor is delivered with built-in thermo sensor. Compressed-air supply is connected on unit by Cejn-coupling incl. ø10mm hose nipple. Easily accessible differential pressure reading in digital display of filter control placed countersunk on unit front. Quicklock-adjustable dust container on 4 wheels ensures user-friendly dust container service.

Can be used for room ventilation/air cleaning and is available with W3-certificateFor cleaning of slightly polluted room air containing e.g. welding smoke Filterline CFL52 and FAL 104 can be deli-vered with mounted air distribution modules that effects extraction of polluted air in top and returning clean filtered air at floor level (recirculation). Filter units with/without selected Airtower modules (CPFL) are available with W3-certificate.

Dust containerQuicklock-dust container system with 35L or 57L-dust container is placed behind bottom front door.

ConnectionsAir is sucked in by lower connection and leaves unit by upper connection.Inlet connection can be mounted right/left.

Automatic and com-pressed-airFilter- and motor control supplied by CEE-plug on front.5.5-6.0 bar dry com-pressed-air is connected by Cejn-coupling incl. ø10mm hose nipple.

Easy filter replacement with limited dust gene-rationCartridge replacement is performed by bayonet suspension, which is loosened from clean air chamber and inserted into sack.
