Filtration cab air quality systems

Since the introduction of the FFTube, this model has been widely used on machines from 3 to 100 tons. The system is characterized by its compact size in combination with the high filter capacity. Part of the technique, that is used, is derived from the FFMultibox. The FFTube takes in the air through the filter medium against the force of gravity, which considerably extends the service life of the filters.

The cylindrical shaped filters ensure that these can not be placed incorrectly. The air is  proportionally distributed over 100% of the filter, and preferential air flows are a thing of the past. The single radial blower in the unit makes less noise compared to other units because the speed is lower at the same air output. The most important feature of the FFTube is its compact size.

Machines are becoming more compact and that has the downside that an cab air filtration systems is less easy to install. The FFTube can be mounted on almost all machines without expensive sub-frames; the unit is only 350 mm in diameter with a height of 420 mm, and can filter up to P3 / HEPA level in combination with 3.3 Kg. active carbon!  The unit can be be optionally equipped with a high hood, when the remediation requires a carbon filter of 10 Kg. This hood can be placed on the base of the FFTube, and can be changed without tools.

The FFMultibox is the most used cab air quality system on excavators, wheel loaders and dumpers. The patented design makes it possible to extend the life of the dust filters to more than 4 times compared to conventional systems. The unit is controlled with one of our control systems, in that way you can always do your work in accordance with the latest regulations.

The FFMultiBox is by far the best system available in the market, whether you are in extreme dust situations or a 3T remediation.

Advantages of the FFMultibox:

  • The suction opening is more than 15 times larger than that of conventional units
  • The filters in the FFMultibox are self-cleaning
  • The service life of filters is more than 4 times longer compared to conventional systems
  • The FFMultibox has three filter detection sensors

The Freshfilter Multibox is supplied with filters in the size 595x395mm, with a filling height of 200mm. In the most common configuration there is a P1, P3 and 11 Kg active carbon filter.

The FFMultibox is also available in an XS and XL variant. The different dimensions relate to the filter size; the XS uses filters of 600x336mm (the same as FFM10), with a filling height of 150mm. The FFMultibox XL uses filters of 595x595mm with a filling height of 200mm. The 3 different sizes of the FFMultibox are all suitable for the heaviest remediation class.

The Freshfilter M10 cab air quality system offers a universal system and can be mounted on every type of machinery.

The unit is designed to fit on top of a cabin, without compromising the view of the cabin operator. The unit is perfectly suitable for installation on forklift trucks, sprayer cabins, excavators, shovels, etc.

The unit can be equipped with a brand-specific adapter for all trucks, or with a hose connection for mounting on the roof of excavators. Regardless of the machine, the dynamically curved surfaces of the M10 are a perfect fit. The unit also has reduced dimensions in order to limit transport height.

The unit has capacity to install HEPA elements, combined with 10 Kgs of carbon filters. This combination will safeguard the operator from toxic gasses and/or silica dusts. The unit is capable of filtering 120m3/h and can filter up to 99,95% removal efficiency, this supersedes the class 4 cabin requirements by far!

The M10 unit features 2x optical filterdetection, IP67 Deutsch connectors, stainless steel (304) enclosure and an UV resistant ABS plastic cover. The spring structure ensures that the filter elements are pressed into their sealing. The FFM10 is operated by the FFController 3000 or 6000 series, and is available in both 12 or 24V.

Thanks to our own developed overpressure systems and the use of parts that have already been developed in the M10, we have been able to keep the price extra sharp – and yet be able to guarantee our trusted quality!

The FFBox is a universal filter overpressure system, for both trucks and excavators. For trucks, the system is fitted with a skylight adapter when installed on the roof. For each brand different assembly sets are available. The signalling system is mounted in the panel inside the cabin, which makes it is easy to operate. The FFBox is equipped with a hose connection for mounting on off-road equipment.

An advantage of the FFBox is the use of cylindrical filters; the end users can no longer make any mistakes with regard to the placement of the filters. The round filter elements fall into each other exactly and therefore there is no need to install filler frames, etc.

The large round filters also give the FFBox a 100% proportional air intake, which results in an optimal dirt loading of the filters; preferential air flows through the filters remain absent.
