The Shand & Jurs Model 94450 Combination Deflagration Flame Arrester and Free Vent provides both positive flame stop and maximum venting in a compact fitting. This Shand & Jurs fitting features an easily accessible, unitized tube bank. It's completely removable for quick inspection and servicing, even under severe conditions of unpredictable corrosion or neglect.

The tube bank consists of passages formed by spirally winding alternate flat and corrugated sheet stock around a solid core. To insure maximum flow, constant tension control is maintained during winding.

The tube bank is contained by its shell between the body and free vent adapter. The hood and adapter can be easily removed as a unit.

Standard body construction material choices include light weight cast aluminum, cast stell, 304 or 316 stainless steel, ductile iron and cast iron. Raised face or flat face flange to match ANSI, EN1092, or JIS connections.

For highly corrosive applications, body and tube bank construction of Duplex SS, Hastelloy C or ALloy 20 are available.

Temperature monitor device to be installed on unprotected side of Tube Bank.
