Fume Cupboard Extraction
& Duct Installation
We have been providing fume extraction and offering duct installation services throughout the UK for over 50 years for any size of project.
Fume cupboard EXTRACTION
Fume Extract Systems
The optimum performance of fume cupboards and ducted containment equipment can only be assured if it is connected to a well designed fume extraction system.
That's why our industry-leading product range is complemented by our specialist team of ventilation designers and fabricators.
Our engineers offer extensive experience in the selection, design, manufacture and installation of all types of fume extract systems including single and multiple ducting for constant or variable volume useage.
To ensure the ultimate performance of our systems, we also offer a comprehensive range of high efficiency, backward curved centrifugal fan units, specifically designed for use with corrosive materials.
Our team at HFH is dedicated to helping you identify the right products and solutions to match your individual project needs.
Our systems are manufactured from chemically resistant materials, typically PVC, Polypropylene and FRPP and they are designed in line with the relevant specifications - DW154, LGC1614 and BS EN14175. All fan units have been fully tested to British and European standards. Full performance curves including noise, power, efficiency and dimensional data are available upon request.
Ducting For Fume Cupboards
For a fume cupboard to perform satisfactorily it must be connected to an appropriate ventilation system which extract fumes efficiently from the fume cupboard and discharges them outside of the building in such a manner that they are adequately dispersed and do not re-enter the building or otherwise present a potential hazard or nuisance or the fume cupboard should be by design a ductless fume cupboard that utilises filters to clean the air.
The air extracted through a fume cupboard is far greater than the normal extract rate of a room or laboratory and to prevent excessive build up of negative pressure within the laboratory which often reduces the performance of the fume cupboard then a balanced make-up air system should be introduced.
This should be designed in such a way that the make-up air introduced into the laboratory should not interfere with the air movement and patterns around the fume cupboard and should still maintain a small negative pressure within the laboratory.
HFH have many years experience in designing and specifying fume extraction systems and we welcome being of assistance to any size of business / laboratory.
