Page 7: Blower Air Intake
BLOWER AIR INTAKE 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, lead to personal injury or death. -

• Higher blower operating temperatures are directly related to higher oil temperatures. • Every Tuthill Vacuum & Blower Systems blower has been factory tested, oil drained, and shipped dry. • Oil reservoirs must be filled to proper level before operation. -
Page 9: Frequently Asked Questions Regarding Lubrication
FREQUENTLY ASKED QUESTIONS Oil Fill REGARDING LUBRICATION What are the perceived modes of failure when units are run beyond Oil Sight the specified duty cycles? Glasses Several things are happening as the lubricant goes through the unit. First, it is absorbing frictional energy in the form of heat. This heat has to be dissipated through either surface contact with Oil Drain cooler materials, or in a rest volume of lubricant. -
Page 10: Long Term Storage
condensation of water can occur after the blower is shut down and the blower begins to cool. This creates an environment favorable to corrosion of the iron internal surfaces, or in cold weather, the formation of ice. Either of these conditions can close the operating clearances, causing the blower to fail upon future start-up. -
