Product Manufacturer: easivent
A skid-mounted unit comprising fans, dampers, and controls designed specifically for smoke shaft applications. Extract fans will be axial high temperature fans manufactured from hot dipped galvanized steel sheet.
The fan assembly will contain a weatherproof discharge, a flexible connector, a gravity shut-off damper, and a galvanized steel plenum section connected to the builder’s work roof upstand above the extract shaft.
The fan assembly will be mounted onto skids fitted with adjustable feet for mounting on a suitably prepared roof area.
The main system control panel is to be located on the fan skid arrangement and prewired to the fans and dampers. The exhaust should be positioned a minimum of 5m from the stairwell vent to prevent smoke being drawn into the stairwell.
All fans are tested to the latest internationally recognised standard IS05801 Part 1, installation category D for aerodynamic performance and BS848 Part 2 (1985) for acoustic performance. The fans and motors are rated at 300°C for two hours and are fully tested and certified to the requirements of EN12101-3. The fans are mounted in series onto a pre-assembled module using anti-vibration mounts.
