Product Overview:

MSI Industrial Fans Series - MZ are suitable for the systems of Central Ventilation, Air Cooling, Air conditioning, Dust Collection, Fume Extraction, Clean Air Rooms, Heating, Hot Ovens, Furnaces, Pneumatic Conveying and various types of Industrial applications. These fans are provided with medium speed double curved (Forward Curve Radial Tip) bladed impeller.

These fans are available in Double Inlet Double Width construction suitable for duct mounting and plenum mounting.

The impellers of Series - MZ fans have wide blades, which are more efficient and very rigid. Also extra width and open tip of impeller blade helps in maintaining low velocity resulting in low noise operation.

The MZ - Series impellers with the dia up to 560 mm are fabricated without Tie - Rods and whereas impellers with the dia from 630 mm up to 800 mm are fabricated with Tie - Rods. The impellers are fabricated in all riveted construction.

The side panels of the housing (Scroll) are deep drawn and are standard part of MSI - MZ double inlet fans. These side panels are provided to reduce turbulence and air noise and increase efficiency. These are particularly valuable to the user when elbows and obstructions on the inlet bend to disturb the proper entry of air into the fan impeller. In addition to the above benefits these inlet cones also act as an effective safety guard without the obstruction to air flow.

The impellers are designed for limit load characteristics and do not consume more power than specified on particular speed irrespective of the air quantity discharged and pressure developed. This provides excellent safety in selecting the motor sizes / ratings.

These fans are provided with double row self aligned ball bearings in Arr. VBD( V. Belt Driven ) and whereas Arr. DD ( Direct Driven ) the impeller is directly mounted on to the motor shaft.

GENERAL:
Forward Curved Blades, developed at our laboratories.
Maximum efficiency up to 70%, depending on the size of wheel, high pressures and large volumes.

Our characteristics curves apply when utilising a fan housing made in accordance with our recommendations, determined in connection with our fan inlets type ED 1 on a MSI standard test bench.

MODELS :
MZ Fans from 250 to 800 mm, made out of galvanised sheet steel, rolled construction, partly with bracings.

Application from -15 degC to 50 degC.

Special executions in other sizes, hubs and materials like e.g. :

1. Aluminium
2. Stainless steel
3. Black iron plate

Direction of Rotation is determined by looking into the suction side of the wheel. Wheel fit of the double flow wheels generally in the clockwise rotating wheel.

BALANCING:
All the impellers are balanced both statically and dynamically to give noiseless and vibration free service.

OUTLET FLANGE:
All the blowers with housings are supplied with outlet flange for easy connection for the supply ducts.

HOUSING - DRAIN:
Half coupling, less plug. Welded in the lowest point of the scroll / housing for cleaning and draining out the water.

PAINTING:
All the blowers are grinded and two coats of anti corrosion resistant primer are applied before given final finish of enamel / epoxy paint as per the customer requirements.

CLEAN - INSPECTION DOOR :
Flush mounted, plate type with quick opening tension latches and airtight with rubber gasket are available optional.

BEARINGS:
All classes of fans are supplied with lubricated heavy - duty self-aligning ball bearings flange or pillow blocks with spherical roller bearings used on larger and higher duty fans. Bearings are selected for continuous operation and ample size for the best possible operating results.
