CAUTION: The size of the openings depend on the heat sources and machinery placed in the room. The
dimensions indicated in Table A are for a compressor PACIFIC 35 M and vary depending on the volume
and height of the room. The height of the room should not be lower than 2.3 meters and the minimum
distance from the top panel of the compressor to the roof must be 1 meter.
If in the same room two or more machines are placed you have to calculate the ventilation adequate for both machines
to work properly. Use the formula on Table C for your calculation.
Volume of Air Intake ( m² ) = Number of Compressors x Volume of Air Required for the Room ( m² ) x 1,6
Tab. C
If the room volume is lower than indicated, and vents for air circulation less than those indicated, it is
mandatory to insert artificial ventilation (see section 4.04)
4.04 ROOM WITH ARTIFICIAL VENTILATION:
In the case of artificial ventilation it is important to check that the fresh air inlet is positioned at the bottom and the outlet
is positioned at the top in two different walls. In the case of extractor fan make sure that the flow rate is equal to or
greater than that indicated by calculation (see Table D).
Minimum air circulation ( m³/h ) = Capacity of the compressor ( l/min ) x 7,5
Tab. D
To ensure that there is sufficient ventilation and that the fan flow rate is adequate simply measure the speed of the
outgoing air (m / sec) and the section of the exhaust duct where the measurement is made (m²) and then calculate it
using the formula in Table E.
Air circulation ( m³/h ) = Cross Sectional Area of the Duct ( m² ) x Air Speed ( m/sec ) x 3600
