GENERAL EXTRACTION
JJ Roof Extract Units are specially designed industrial roof extract terminals manufactured from heavy gauge aluminium for reduced weight, corrosion resistance and to withstand harsh industrial atmospheres for a prolonged service life. Each unit is equipped with back-draught shutters to prevent rain ingress and winter heat losses when not in operation.
JJ Low Profile Roof Extract Units are general purpose high performance roof extract terminals providing constant positive extraction of vitiated air from industrial applications.
JJ Vertical Discharge Roof Extract Units are designed to remove high volumes of waste heat and fumes from industrial applications and project them vertically away from the building for rapid dispersal.
Both Low Profile and Vertical Discharge Units are available in various sizes and fan speeds to suit individual requirements. In addition, inverter controllers are available for optimum versatility.
Typical applications are for waste heat removal and also for the removal of warm buoyant fumes such as diesel fumes, welding fumes and steam.
FRESH AIR INLET
JJ Roof and Wall Inblo Units are specially designed modular air inlet units with a wide range of standard modules to suit individual air supply applications.
These units are specifically used to inject cooling streams of outside air into the workplace to promote freshness and air circulation in otherwise stale working environments.
These units are manufactured in two sizes with standard modules available for each size.
Typical uses are for general fresh air inlet, spot cooling and positive pressurisation.
