The removal of stale, and often very warm, air can promote fresher, healthier conditions in production areas. For example, the installation of simple roof extraction fans will reduce temperatures and allow fresh air to enter the building. Preferably, incoming air will be fan assisted and filtered - providing a fully balanced and controlled system. Incoming air can be distributed through a ducted system of discharge grilles, or more simply introduced through porous fabric media e.g. discharge socks.
Filtermist Systems’ team has extensive experience in delivering fully sealed systems which control air pressure in enclosed environments. This includes tempered air used in test cells, and air which is put under positive or negative pressure for use at altitude or below sea level.
For minimal extra cost, cooling can be introduced into ventilation projects with the use of evaporative cooling units. These units are ideal for the provision of operator “comfort” and “spot” cooling. Our evaporative cooling systems are a natural and cost effective solution to high temperatures in the work place, providing large volumes of cooled air for spot cooling or general ventilation.
We can supply an extensive range of Metmann coolers and accessories ranging in size from 2,500 m3/hr to 63,000 m3/hr. Units can be supplied with bodies in stainless steel or polyamide.
Evaporative cooling uses the principle of adiabatic cooling to provide cool air, (typically five or six degrees below ambient temperatures), at relatively low cost compared to air conditioning. Operating and maintenance costs are also significantly lower than comparable air conditioning plant.
As with general ventilation, the incoming cooled air can be distributed through a ducted system of discharge grilles, or more simply introduced through porous fabric media e.g. discharge socks.
Machine ventilation can be used to capture and re-distribute what would otherwise be waste heat, e.g. the output from compressor cooling fans can be ducted into areas where this heat serves a useful purpose – so reducing the overall costs to heat a factory.
We supply numerous types of ducting to fit almost any application including pipe work vacuum systems. We use various types of circular and rectangular ductwork which incorporate a number of jointing methods. These include: spirally wound, longitudinal seamed, lockformed, fully welded, slip jointed, flanged, clip jointed and quick release and are manufactured in galvanised, mild steel, painted or stainless steel.
The ductwork we supply includes FastClip which is manufactured in the UK by Filtermist International Limited. We also specify ducting from other suppliers for specific projects when required.
