Description
- 225mm x w-175mm x d-100mm x 150mm diametre.
- 6.5m3 (6.500 litres) of damp air extracted from your sub-floor per minute.
- Retrofits a 2 brick high terra-cotta vent.
- Operates at 49.7dB@1m (twice the dB rating of the quad fan system, but for similar ventilation systems, has about the same dB rating).
- Available in Brown, White, Shale Grey & Woodland Grey
- Long life – fully serviceable.
- Low voltage (12v – 13.2v) or solar powered.
- IP67 rated
- Australian made.
- 2 years manufacturers warranty.
- Digital timer is recommended.
Advantages:
- 12 volt system operates at 19.2 watts. This would mean the impact on power resources is much less than a 240v system which would reduce the carbon footprint.
- This system can be solar powered. (Would require 2 panels)
- This sub-floor ventilation system can be used as a stand alone product without the use of the flexible ducting.
- There is no need for an electrical license as the unit is low voltage. This would be ideal for the home handyman, pest technicians, plumbers, carpenters and builders.
Application:
The end of the duct can be positioned in the sub-floor where the musty smell is noticeable inside the dwelling and should be targeted where it is most pronounced. This can be verified by accessing the sub-floor area to determine that the musty smell is more concentrated in this area.
If the sub floor space has a minimal space whereby a brick size ventilation system cannot be fitted on the outside wall due to elevated ground levels equal to or above the sub floor area, then the EF12SQR-150 which integrates the fan motor into the square to round 225 x 175 can be mounted into an existing terracotta vent or via a new opening in the brickwork, then the ducting is extended back into the sub-floor area where it is needed. The EF12QR-150 will accept 150mm flexi-duct or 150mm PVC plumbers pipe. Maximum length of ducting shall be no more than 6 metres. If desired may be used with no ducting.
Similar in principle to our In-Line and Cul-de-Sac ventilation systems, the EF12SQR-150 is ideal for dwellings with a minimal sub-floor space, and where a typical Quad Fan or Dual fan system cannot be installed. However, this Envirofan fan-forced ventilation system is for cases with limited ability to install on the exterior wall where the outside ground level impinges on the sub-floor area thereby the EF12SQR-150 can be moved at a position on the exterior wall and the end of the ducting postioned toward the area that needs to be serviced. Length of ducting cannot be more than 6 metres.
