Air Movers If compressed air supply is available, air movers can be used to generate localised air movement without the need for an electrical power supply.
110V Fans Hand portable, featuring a rugged plastic casing ideally suited for site use. Can be used with 12” flexible duct for general air movement.
‘Super Silenced’ Ventilation Fans For projects where noise can play a major role, these ventilation fans are housed in a ‘super-silenced’ enclosure to keep fan noise at an absolute minimum.
Jet Fans If the tunnel is open at both ends, a jet fan can be used to maintain a consistent air flow throughout the tunnel. These fans run without ducting.
Centrifugal Fans When using small diameter ducting (such as with Pipejacks), a higher pressure fan is often required. Centrifugal fans are ideally geared towards this application.
Ventilation Design Specialist Plant Associates supply robust temporary ventilation systems to suit any tunnelling or civil engineering application. With years of experience in construction ventilation, we can offer to design your ventilation system for you, to ensure full compliance with all ventilation requirements and regulations for air quality, NO/ NO2 and dust.
Inverter Drives We can supply Ventilation Fans equipped with inverters, to give variable speed control.
Ducting Semi-rigid ducting can be supplied to suit any application, whether that is suction or forced ventilation.
Rigid Bends & Support Frames Rigid bends can be used in place of flexible ducting to maintain airflow and prevent duct collapse, particularly at the top of the shaft. These can be attached to support frames to bolt the bend to either the floor (at the top of a shaft) or to segment linings.
Anemometers Used to measure air speeds. Hot wire- low speed range, high accuracy. Used to measure airflow speed in tunnels/headings. Vane anemometer – Higher speed range. Used to measure airflow speed at duct outlets / fan inlets
Vertical Mixer / Pumps Our most popular model, with large mixing pan and built-in pump with output pressure up to 12 bar. Air powered, giving infinitely variable speed. Can also be used for Bentonite/Sloop. speed at duct outlets / fan inlets
