FORESTAIRE+

Forestaire + pressurisers provide filtered air inside the cabin to protect you or your vehicle operator from harmful asbestos or silica dust, or chemical or organic pollutants.

The unit works by drawing in air from the atmosphere, the air moves into a cyclonic orbit which displaces the heavier particles to the outer orbits to eject back into the atmosphere.  The finer dust particles are then captured by the fine HEPA filter. A return air vent also draws air out of the cabin to ensure that any dust from the operators clothing or boots etc is removed and filtered.  The MERV and HEPA filters ensure 99.97% of harmful debris is removed from the cab.

These systems comply with clean air regulations worldwide. The highly efficient fine HEPA filter H13 meets BS EN1822 STANDARDS

Advantages of our unit

  • Fewer service intervals
  • Less filters required over service life of machine
  • Less filters containing asbestos requiring disposal reducing cost as these need to be disposed of in line with current environmental regulations
  • Less safety equipment required, therefore less logistical issues in disposal or cleaning of dirty PPE
  • Less personnel required and exposed to Asbestos during servicing

The primary or Merv filter is expected to last approximately two years dependent on the application. The working environment i.e. exposure to dust, type of machine and application will affect the life of the actual filter element and the ability of the media to withstand the specific environment.

The HEPA filter is expected to have a life expectancy of up to five years, depending on the specific environment of the machine and the area it is working in.

Features of the system

The Forestaire + is extremely robust and perfect for use in mining, quarries, construction or forestry equipment and can be fitted to Caterpillar, Komatsu, Liebherr or any other brand of heavy equipment.

Heavy Aluminium construction ensures these units withstand the most serious damage. There are minimal flat surfaces to prevent dust build up. The units are sand blasted and powdercoated with a high temperature two step procedure to provide as much protection as possible against the environment. All assembly uses nitrile gaskets where necessary and all fastenings are stainless steel to give serviceability over as long a time span as possible.

The flashing light supplied as standard is high quality, manufactured by PRECO in the USA and incorporates LED technology and a brushless motor. This light has proven to have extremely high visibility on the units currently in service.

Interconnecting ducting is TPR vulcanized rubber this is a double layer ducting that is installed to provide resistance against abrasion and has a very high UV resistance.

It is our intention to be able to supply full interface kits for most machine types as we progress through the various installations, but the systems come with a basic field fitting kit that includes ducting and cab termination flanges.

Each system has a separate dash display in a sealed enclosure with generic mount bracket. Each display shows actual cabin pressure and red flashing indicator light.

The controller is manufactured using proven componentry already in use in the HVAC industry and has been chosen for its robust capabilities. The controller is a microprocessor based system which will allow future adjustment of all settings to meet application requirements specific to customer’s needs. The controller is housed in a sealed dustproof enclosure and is available with the correct interface for cab mounting to specified machine types. The controllers are essentially plug and play although commissioning is done on all machines to ensure pressure and fan speed are correct for the application.  All wiring is supplied with the unit with receptacles on the controller for connection. As it becomes available connection information for each machine will be included. The unit is connected using weatherpack plug connections field fitted during installation.

As an added advantage because all units are identical it is expected that spare units will be held in stock by the customer and should there be an issue with a unit in the field, rather than opening it in an uncontrolled environment, simply by unplugging three plugs, two hose clips and four M10 nyloc nuts the unit can be changed out. There by limiting exposure of service personnel to asbestos.

Do you have a light commercial vehicle working within earth moving, agriculture, forestry, quarries or mining industries? Our Cabaire Pressurisers may suit that vehicle better.
