SB vents saves total electricity used for power exhaust system. Round the clock it works without any expenditure. One unit saved is two units produced, you are saving your nation.

3. SB VENTILATORS VS CONVENTIONAL VENTILATORS ACI TURBO VENTILATORCONVENTIONAL VENTILATORS Non-conventional energy saving systemConventional energy system required. No electricity bills. Cost of Ventilator is recovered in the first year itself. Electricity bills are a monthly feature. Increasing cost of electricity makes electrically operated-ventilator a costly proposition. Not required heavy structures on roof. Heavy structures have to be mounted on the roof. Vibration-free operation Roof becomes weak due to vibrations with Conventional ventilators Assured operation for 24 hours a day, 365 days a year Can operate only when power supply is available & needed No maintenance costs as there are not armatures / field coils/switches.
