Armfield - Fluid Machines - FM Series CAPTURE

The FM40 is a radial flow machine, which produces the necessary pressure to move gas by the centrifugal force built up inside the fan casing. The design of the fan blade has a primary influence on performance.

These types of fans are usually employed for ventilating duties requiring a somewhat higher delivery pressure than that available from axial fans.

Key Features

• ​A small-scale centrifugal fan demonstration unit, comprising of an inlet duct, the fan, an outlet duct and an adjustable aperture, all mounted on a stainless steel base
• Equipped with electronic measurement sensors for fan head pressure, flow rate (via orifice plate) and air temperature
• Transparent cover plate on fan volute for visibility
• Supplied with two different, easily interchangeable impellers
• Capable of being linked to a PC (not supplied) via a USB interface console (an essential accessory), which does not require internal access to the computer Also enables interfacing to other software packages
• Supplied with software providing full instructions for setting up, operating, calibrating and performing the teaching exercises. Facilities for logging, processing and displaying data graphically
• Offers a complete teaching package of coursework and laboratory investigation

The FM41 produces gas flow by virtue of the momentum changes imparted across the rotary blades, parallel to the axis of rotation. Such fans are more suitable for higher flows at lower delivery pressures than their centrifugal counterparts.

Comparison of the performance characteristics of the FM41 Axial Fan with those of the FM40 Centrifugal Fan thus provides an instructional exercise of valuable practical application.

Key Features

• ​​A small-scale axial fan demonstration unit, comprising of an inlet duct, the fan, an outlet duct and an adjustable aperture, all mounted on a stainless steel base
• Equipped with electronic measurement sensors for fan head pressure, flow rate (via orifice plate), fan speed and air temperature
• Transparent ducts give visibility of the fan in operation
• Capable of being linked to a PC (not supplied) via a USB interface console (an essential accessory), which does not require internal access to the computer. Also enables interfacing to other software packages
• Supplied with software providing full instructions for setting up, operating, calibrating and performing the teaching exercises. Facilities for logging, processing and displaying data graphically

The FM42 demonstrates, on a small scale, the use of a multi-stage centrifugal compressor, as used in industry for high pressure deliveries of gas flows or suction duties.

Multi-stage compressors are used industrially for high pressure deliveries of gas flows or suction duties. The kinetic energy imparted to the gas by the impeller rotation is converted into pressure energy, which progressively increases from stage to stage.

Key Features

• A small-scale multi-stage centrifugal compressor demonstration unit, comprising an inlet duct, the compressor, an outlet duct and an adjustable aperture, all mounted on a stainless steel base
• Seven stages in the compressor
• Equipped with electronic measurement sensors for head pressure, flow rate (via orifice plate) and air temperature
• Capable of being linked to a PC (not supplied) via a USB interface console (an essential accessory), which does not require internal access to the computer. Also enables interfacing to other software packages
• Supplied with software providing full instructions for setting up, operating, calibrating and performing the teaching exercises. Facilities for logging, processing and displaying data graphically
• Offers a complete teaching package of coursework and laboratory investigation, complete with a student questions and answers session
