Ampelair Industrial Ventilators

Overview
The Building Code of New Zealand sets out minimum ventilation requirement for industrial and commercial premises. However depending on the building use this can be less than adequate.  It is generally recognised that workplace efficiency is improved when ventilation matches the interior conditions.  Extracting oppressively hot air and fumes minimises worker lethargy, loss of concentration, and consequent loss of productivity.  Even in colder weather, effective air circulation improves the workplace environment, so your investment works all year. 

Round Vane (RV) Industrial Range

Ampelair RV Industrial Ventilators are engineered and constructed to require very little maintenance even after years of service. With their low profile design and aluminium construction, Ampelair ventilators are designed to give optimum efficiency through the angle of the vane and the enlarged surface area.  Even in cross winds the vane shape will retain its rotational strength.

    Straight Vane (SV) Industrial Range
    Ampelair SV Industrial Ventilators suit new installations or replacements for large commercial and industrial applications. Aluminium construction with throat sizes from 450mm to 900mm, every industrial building large or small needs to keep air circulating and keep temperatures to a comfortable level. Ampelite SV ventilators are an effective, reliable, maintenance free ventilation solution. Using only the power of the wind they extract stale air and allow fresh air to circulate.

      Number of Vents

      Calculations to decide the number of vents.

      1. Determine the volume of the building. (Fig. 1)
        Volume of section A = 0.5 x L x W x Ha
        Volume of section B = L x W x Hb
        Total building volume = Volume of section A + Volume of section B
        Note: For factories, the combined volume A + B should be used.
        Where Volume B is air-conditioned, only Volume A is used to calculate the number of ventilators required.  No air should be drawn from the air conditioner space.
        Using ventilators in the ceiling space of air conditioned building reduces the load on the air-conditioning plant and helps reduce power consumption.
      2. Select the number of ventilators required:
        METRIC  = V x A/ch
                        EX/c x 3.6
        Where:
        V = volume of building or roof space
        A/ch = air changes per hour
        EX/c = Exhaust capacity of ventilator

      Consideration should be given to the space occupied by stored goods or machinery.  The adjustment to volume can reduce the number of vents required by up to 50%.
