Industrial ventilator - MoffittVent
MoffittVent provides continuous extract ventilation for most kinds of industrial buildings, providing high volume ventilation. It is aerodynamically designed to provide continuous weatherproof ventilation. MoffittVent can be used on both smoke control and climate control projects. The unit can be adapted to accept sound absorbers.
Features and benefits
Wide range of applications - FCO is generally installed in the vertical for either air inlet or extract. Polycarbonate and glass versions allow the entry of natural daylight. FCO is also often used as a termination piece for large ducted or air handling systems. There are pneumatic, electronic or hand controls and a wide range of louvre types, accessories and finishes.
High performance - FCO is aerodynamically efficient and has a high resistance to weather.
Easy to install - FCO is delivered fully assembled to site. It has a wide range of base profiles to suit most kinds of curtain walling, glazing or prepared openings.
Durable - FCO is manufactured from tough, corrosion resistant aluminium alloy, grade 3005 in accordance with EN573-3, with stainless steel fixings. Louvres pivot on double nylon UV- resistant bearings.
Quality of manufacture - FCO wall vents are manufactured under the ISO 9001 quality standard. Each unit is given a functional test before despatch.
Design service - Colt provides a pre-order design service.
Performance of FCO vents varies depending on size and options selected
- Aerodynamic coefficient: Up to 0.68
- U-value: Up to 3.2 W/m2/K*
- Sound insulation: 9.0-11.0 dB R’w
In many cases a U value of at least 3.5 W/m2/K is required to meet local regulations. Colt can advise on how to achieve this.
Frame manufactured from corrosion resistant aluminium alloy grade 3005 in accordance with EN 573-3, with stainless steel fixings. For installation in the vertical only. Not tested or certified for smoke control ventilation.
Dimensions / size range
- Twelve width options from 426mm throat width to 2326mm throat width.
- Twenty two length options available from 658mm to 3451mm throat length.
Depending on the application, louvres made from:
- Single skin aluminium
- Single skin wired glass
- Single skin laminated glass
- Single skin toughened glass
- Insulated double skin aluminium
- Twin wall clear polycarbonate
- Twin wall opaque polycarbonate
Seals are either low-loss brush seals (for aluminium louvres) or rubber seals (for glass or polycarbonate louvres), which reduce air leakage when closed.
- No seals
- Low-loss brush seals (for aluminium louvres)
- rubber seals (for glass or polycarbonate louvres)
These reduce air leakage when the ventilator is closed.
- Louvres set within the ventilator body
- Louvres protrude from the front of the ventilator when they open
Colours/ finishes options
- Painted to a RAL colour
- Mill finish
Suitable for fixing either into curtain walling, glazing or prepared openings.
- 230V AC
- 24V DC
For both electric and pneumatic versions, either double action locking mechanisms, failsafe open or failsafe closed.
If used as either an electric or a pneumatic smoke ventilator, activation is either by local thermal fuse which opens the unit at a pre-selected temperature, or by responding to an external release signal.
