Compact filters

Products / Compact filters

IMAS AEROMECCANICA, in addition to designing, building and installing complete systems for dedusting and purification, has launched a series of Compact filters, equipped with electrical panel, filtering system and everything necessary to enclose in a single solution, everything needed to sanitize the air in the workplace and release polluting factors into the atmosphere below the legal limits. Particularly suitable for the Filtration and Purification of the most diverse polluting factors, such as whole and emulsified oils, powders of different granulometry, very thin dry or low humidity powders, composite materials, etc., deriving from processes such as hot or cold metal molding, rather than heat treatments, metal finishes, woodworking and inert materials, plastic, rubber, etc.

Filtration systems and application sectors

Suction workbenches with cartridge filtration and counter-current cleaning with compressed air, complete with electro-aspirator with anti-spark nozzle, ATEX motor and electrical panel, are suitable for the extraction of fumes or dust produced by welding, grinding, sanding, sanding , on small or medium-sized products, with a maximum weight of 250 kg / m2. The support surface is equipped with holes designed to ensure uniformity of suction and can be easily replaced to adapt it to different operating needs; they can be completed with a suction and extractable front wall and side containment modules. Built inside the IMAS AEROMECCANICA factories, in Fe 360

"CMA" Suction booths with cartridge filtration and counter current air jet-pulse for the cleaning. These suction booths contain a completely soundproofed electric fan with spark proof inlet, ATEX motor and electrical panel and are suitable for manual processing of products, even large ones, which generate fine suspended dust. Designed in nominal modularity of 2 and 3 m (2.26 m and 3.39 m effective), they can be expanded as they are extremely modular. Manufactured in-house at IMAS AEROMECCANICA Srl factory they are suitable for sanding, polishing, sandblasting operations, application of paint powders, etc.

For grinding and polishing operations, they are available in a specific, sound-absorbing version (CMF), whose front panel has a sandwich structure consisting of a sheet metal base, a high-density fibre foam pad and a perforated sheet metal protective cover; the suction section has a metal pre-filter with anti-spark function and self-extinguishing cartridges. The modules that make up the partition walls or the roof have the same sound-absorbing composition, for overall attenuation of acoustic reverberation. The filtering system is based on antistatic cartridges with filtration efficiency of > 99.99 %, whose cleaning is entrusted to a cyclic timer (STR), with programmable pause/run times and an integrated timer for the post-cleaning function, with an approximate system noise level of 78 Db (A). The treated air can be returned to the environment with consequent energy savings.

DAP series represents the ideal solution for the aspiration and filtration of different dust types (composite materials, metal, wood, plastic, etc.) produced by processing which require high or very high pressure; For pressure until 4.500 Pa and air delivery until 2.000 m3/h, the models DAP 40 and DAP 75 are perfectly suitable, equipped with high efficiency electro-fan. For more performing applications (high vacuum), for pressure until 20.000 Pa and air delivery until 1.000 m3/h the models DAP150S and DAP185S guarantee these performances thanks to the equipment of very high pressure and efficiency blowers.

All DAP models are made of welded and painted sheet and equipped with:

“CO” dust collectors with horizontal cartridges, working in depression with cleaning of the compressed air filters in counter-current controlled by a sequencer. Mainly used for indoor applications, they are suitable for the treatment of powders with reduced particle size with concentrations between 3 and 5 [g / m3]. Manufactured under ISO 9001 quality control in IMAS plants, they are supplied fully assembled after being painted with epoxy powders polymerised at 180°C. The electric aspirator, positioned at the rear in a completely soundproofed compartment, is equipped with a high-performance impeller and an electrical panel on the machine.

The dusty air enters from below, directly into the hopper equipped with a non-return valve, the heavier material settles directly into a 160-liter container, which is equipped with wheels and quick-coupling hooks. The lighter material is dragged by the air flow towards the filtering media and is subsequently detached by the compressed air jet, due to the size of the valves. The "TF" versions with PTFE membrane cartridges are specifically designed for the suction of Laser or Plasma cutting benches.

Dust collectors with sleeves or cartridge filtration, operating in depression and cleaning of the compressed air filters in counter-current managed by a sequencer. Equipped with a stilling chamber extended along the entire length of the filtering battery, they are mainly used for internal usage, suitable for the treatment of fine, dry or low humidity powders, and are specific for the suction of laser or plasma cutting benches. Built under ISO 9001 quality control within IMAS AEROMECCANICA Srl factories, they are supplied fully assembled after a painting cycle. Inspection and any maintenance are facilitated by the large upper door that can be opened by means of gas cylinders; The inlet of the sucked material takes place from the side, directly into the large stilling chamber and then decanted into the hopper and then into the container.

The same coalescence principle of working so far applied by IMAS AEROMECCANICA to big installations is now proposed also for little depurators series
MCH Functional working - The sucked air enters the depurator through the expansion chamber; the drop in speed causes a fall in kinetic energy , this making the biggest particles fall down into the collecting tank equipped with anti-turbulence interspace. The second stage consists of a metallic pre-filter having optimized section agglomerating the polluting substance and retaining any eventual silicate (solid particles). This pre-filter is easily removable and washable, and its state is indicated by an outer manometer. The third stage of filtration, the heart of the depurator, consists of a self-draining coalescence candle made of a series of pierced metallic cylinders, inside which are placed the compressed glass fibres, disposed by alternating variable sizes between 6 and et 12 microns The filtration, based on the Brownian diffusion principle of sub-micron particles, guarantees an efficiency degree of more than 96-98%, and this with no need of any maintenance or replacement operation. During draining oil is collected in a suitable integrated tank, from which it will be evacuated automatically by means of the Clapet valve. The depurated air goes through the fan – which is then crossed by clean air – and is conveyed towards the final filter (HEPA H14 EN 1822 efficiency 99,99%), which also serves as a diffuser. The high efficiency degree reached by the candle guarantees a long life to the HEPA filter, the state of which is controlled by a differential pressure gauge with alarm warning light. The depurator is equipped with electric board for motor control and protection, having pre-arrangement for remote start contacts, and working hours counter.
