Double Inlet Centrifugal Fan with Airfoil Backward curved blades, with welded casing.

The centrifugal fans MAZ, equipped with airfoil blades impeller can be considered a variant of the present series TZAF FF and NTHZ , equipped with a fully welded, reinforced housing.

The housing structure is made by black steel sheets, reinforced with steel stiffeners, completely welded and painted with corrosion-proof epoxy paint.

Bearing support is designed as a separate component, and can be fixed in four different positions to optimize belt installation. It can be easily removed, as the inlet cone, for an easy access to the impeller, leaving the housing in place. The optimal working area is within 90 and 100% of the maximum rpms, with a consequent reduction of the fan vibration levels.

Three different sub-versions are available as standard, T1, T2L and T2. On request, special executions are possible, when increased performances are requested. Stainless steel and hot dip galvenized versions are also available.
