Washing tower – SCRUBBER

Washing tower SCRUBBER

Washing tower - SCRUBBER

The scrubber is a filtering device to abate the concentration of VOC and dust found in gas streams. It is used when the substances to be removed react in water.


Abatement takes places through impact between the nebulised washing liquid and the pollutants in the air. The polluted air is suctioned into the lower part of the washing tower and is washed in counter-current at low speed over a broad contact surface.


Wet abatement systems can be composed of several washing stages, even with different types (e.g. Venturi scrubber, floating washing tower, static washing tower, horizontal scrubber) and with different washing solutions according to the pollutants to be removed and their concentrations.

Oil mist coalescence filter – MCOS

Oil mist coalescence filter MCOS

Oil mist coalescence filter
MCOS

MCOS is a filtration system designed to separate oil and smoke particles from the air in particularly heavy duty work conditions, using the principle of coalescence. Applications for this type of filtration are heavy duty mechanical processing.

The air flow passes through the multilayer fibreglass filter element at low speed, where the coalescence process takes place. By crossing the increasingly thick layers of filtering material, the microparticles of the pollutants are agglomerated, reaching macroscopic dimensions.

What is the coalescence principle? Coalescence is the physical phenomenon through which liquid droplets, gas bubbles or solid particles come together to form larger entities.

Unlike traditional static filters, the coalescence filter does not work exclusively based on clogging, as the particles reach a weight that causes them to fall by gravity into the collecting tank, significantly increasing the useful life of the filter. Once the filter element has been crossed, the air flow goes back to the next element at a low enough speed to avoid dragging the finest particles. To ensure a higher level of purification it is possible to install an additional absolute filtration stage (FFA),with an efficiency rating of 99.99%.

The collected oil particles are expelled through a drain pipe positioned on the back of the filter.

Oil mist static filter – MIST COMPACT™

Oil mist static filter
MIST COMPACT™

The new CLEANMIST PRO range includes a series of centrifugal filters for oil mist. Designed, engineered, and patented, the new CLEANMIST PRO range offers high performance, superior efficiency, and ease of maintenance.  

Polluted air is drawn in through the inlet via the centrifugal motion of a bladed impeller equipped with controlled-density bulpren panels. As the air passes through these panels, the particles undergo a coalescence effect, turning into droplets that are then drained outside through a dedicated discharge pipe.  

A subsequent filtration stage, utilizing the physical principle of coalescence combined with an FFA fiberglass filtering medium, ensures an efficiency of 99.99%, a figure supported by tests conducted at production sites by accredited laboratories.

Cartridge filter – PULSATRON COMPACT™

xr:d:DAF1Y4ndUvs:18,j:2950268308245228522,t:23112721

Cartridge filter
PULSATRON COMPACT™

The Pulsatron Compact® range includes a wide variety of compressed air self-cleaning high efficiency cartridge filters that can solve all dry filtration problems.

Polluted air goes into the filter through a pre-chamber that helps separate the coarse particles; the flow then goes through the cartridges, depositing the contaminant outside of them, while clean air is delivered through the filter head.


An automatic cartridge cleaningsystem maintains the suction capacity, washing them by blowing compressed air that directs the dustinto the specific collection drawer or bin.

The limited dimensions and minimal noise of the filter mean it can be installed even inside departments near the sourceofpollution.

Cartridge filter – PULSATRON COMPACT™ ATEX

Cartridge filter
PULSATRON COMPACT™ ATEX

Reliable and silent, Pulsatron Compact® ATEX is a high efficiency self-cleaning modular dust remover cartridge filter suitable for continuous cycle industrial use.

PC® ATEX series filters are designed for industrial applications where dry dust filtration through the principle of physical separation in qualified Ex II 3D environments is required.

The air being treated enters the filter, through a pre-chamber which helps separate the coarse pollutant particles. The air flow then passes through the filtering cartridges, depositing the contaminant outside them, while the clean air is discharged from the upper part of the filter. A cyclic device manages the cleaning of the filter elements with a Pulse-jet system.

IThe Pulse-jet cleaning system consists in the counter-current injection of a high pressure air flow to remove the dust from the filtering elements without interrupting operation. In the event of an explosion, the vent panel mounted on the filter body mechanically collapses by venting the overpressure generated inside the filter upwards.

The design has been created in collaboration with ATEX standard experts and using cutting edge software (Cosmos, Fem and Solid Works3D) that made it possible to carry out simulations to offer Pulsatron Compact ATEX high resistance.

Dust separator – PC CYCLONE

Dust separator PC CYCLONE

Dust separator
PC CYCLONE

The PC® CYCLONE is a pre-separator which, through centrifugal force, considerably reduces the presence of coarse dust particles.

PC® CYCLONE is used as preliminary treatment of the contaminated stream to partially abate the polluted elements in the air. The standard HFiltration cyclone supply includes the dust collection bin up to Ø1000 mm. To promote the discharge of the abated dust, in addition to the Ø1000 mm, a motorized rotary valve is installed by default below the cyclonic cone.

We suggest using the PC® CYCLONE dust separator as a pre-dust suppressor, paired with our Cart, HJL Bag or Pulsatron Compact® filters. Recommended for a wide range of industrial processes where dry dust and coarse dust or sparks must be treated. The head loss in these cyclones varies between 95 and 130mm H2O.

For heavy duty applications, the pre-separator can be made of wear-resistant steel (HARDOX®).

Horizontal cartridge filter – PULSATRON H

hfiltration-pulsatrion-h

Horizontal cartridge filter
PULSATRON H

The PULSATRON H cartridge filter is a Pulse-Jet self-cleaning modular dust remover with pneumatic cartridge cleaning by blowing compressed air against the flow.

The pleated filtering elements are extremely efficient and abate 99.95% of 0.5µm particles, easily ensuring emissions of less than 1mg/Nm3. 

The specific horizontal cartridge configuration allows there to be a descending air flowmaking the unit particularly suited for treating very light fine dust. Horizontal cartridge filter maintenance is carried out from the front and this makes cartridge replacement extremely quick and simple.

Cartridge cleaning is controlled by a sequencer panel that starts the washing cycle; this happens when the pressure drop through the filter reaches a preset value. Cleaning ends when the pressure drop falls below a second threshold: all the washing parameters (Δp of cycle start/start, Δp of clogged filter alarm, duration and frequency of the puff of compressed air) are adjustable based on the operating conditions.

Hydrodynamic FilterIDRODUST COMPACT

Hydrodynamic Filter IDRODUST COMPACT

Hydrodynamic Filter
IDRODUST COMPACT™

Hydrodynamic filter for dust, vapor, and gas suppression that utilizes the effect of micro-mixing of air to be treated with water.  

Equipped with an innovative design, the machine uses spray nozzles in the pre-chamber to filter out macroparticles and collect them at the bottom of the tank. Subsequently, in the Venturi throat, a centrifugation process occurs through the use of a second set of nozzles, enabling the microfiltration of residual polluted particles. This increases filtration efficiency while reducing the complexity of the initial setup. 

Before being expelled the clean air passes through a droplet separator, where remaining water particles in the airflow are deposited. The cleaning of the droplet separator is simplified by the presence of a third set of nozzles, allowing thorough cleaning without the need to remove it from the main body.
