Selas Multiflo™ Mixer
Selas Multiflo Mixers (Product No. 2331, 2332) are patented design adjustable high efficiency proportional mixers.
Selas Multiflo Mixers are patented design adjustable high efficiency proportional mixers. The energy of the air passing through the jet produces a suction to entrain a combustible gas and deliver the mixture to the burners.
The patented Air Adjuster provides wide capacity ranges in the same size mixer. A simple hand adjustment changes the air capacity and matches the mixer to the burners.
The Multiflo Mixer uses a Zero Regulator (See Bulletin 5101) to regulate the gas flow in correct ratio to air flow. A butterfly air valve (see Section 1) in the air lines is used to vary air flow and heat output of the mixer. This valve maybe operated by automatic control devices.
