4. 4 5 COOLING AIR INTAKE AND DISCHARGE To minimize maintenance supply your blower with the cleanest air possible It is important that the air does not contain any flammable or toxic gases as the blower will concentrate these gases This could result in damage to the unit and surrounding property and lead to personal injury or death The louvered area in the rear of the PneuMax II enclosure provides blower air intake on atmospheric inlet systems and air intake for the cooling fan Do not block or restrict this opening or the blower and or motor may overheat and fail The supply air for the cooling fan is provided through the blower air intake louvers located on the lower side of the PneuMax II enclosure Do not block or restrict this opening or the blower and or motor may overheat and fail Likewise the cooling air discharge located on the upper side of the PneuMax II enclosure must be free from restriction or blockage Any ducting or louvering must not exceed 25 inches of water column 60 Pa static head Excessive restriction to the discharge cooling air will cause the blower and or motor to operate at elevated temperatures possibly resulting in overheating and failure Ducting of cooling air to the unit is not generally recommended Do not use air blowers on explosive or hazardous gases Each size blower has limits on pressure differential running speed and discharge temperature These limits must not be exceeded Consult the manual
