Bell & Gossett Airtol ATF-12 Cast Iron Tank Fitting, 1/2", FNPT x FNPT Airtrol tank fittings help establish the proper initial liquid level in the compression tank when filling the hydronic system. They help maintain proper system pressurization by directing released air to the compression tank during system operation and permit cooler liquid flow to the boiler during the off cycle as system liquid cools. Airtrol tank fittings must be used with the appropriately sized in-line airtrol or rolairtrol air separator.

Aquastat controllers are immersion type devices for limiting or regulating the temperature of liquids in boilers, storage tanks, and other applications where temperature control is required. Honeywell's L4006 are used in applications that utilize the existing wells.

• Totally enclosed micro switch snap-acting switches operate on temperature rise to setpoint
• Visible control point scale and external adjustments screw permit easy setting
• Direct or well immersion of the sensing element
• Remote bulb model may be used to sense air temperature in ducts and in outside air sensing applications Honeywell L4006A2007 High or Low Limit Immersion Aquastat Controller, 100 - 240 deg F, 5 - 30 deg F DifferentialSid Harvey Item #:C290A: Replaces Part #:'s : AQU4006A1678-C290 | AQU4006A2007-C290A | C290 | C290R |,
