Air/Gas Mixers Manufacturers

Air/gas mixers are designed for low-pressure drop operation. Combustion air delivered through a control valve is metered through a precision machined orifice. Controlled air pressure is impulsed to the top of the gas balanced zero regulator. The zero regulator outlet pressure is always the same as the controlled air pressure. An adjustable gas orifice sets the gas fuel flow rate. The pressure interlocked system maintains equal air and gas pressure drops at all flow rates. Air-gas ratio is constant over the entire turndown range of the system. These mixers selections are based on blower air pressure available, mixture pressure required at the burners, BTU/hr. input, percentage primary aeration and turndown ratio required.
