Ventilation means renewing the air in a building or plant, removing contaminated air and, where needed, supplying air to a process. The roof extractor on a factory, the jet fan und... More Details

Green bricks and tiles leaving the press must lose most of their water before entering the kiln; if this water is not removed slowly and evenly, the product cracks or warps. In the... More Details

A plug fan is a centrifugal impeller without a scroll housing, placed in an open chamber (plenum) inside an air handling unit or ventilation cabinet. Because the impeller sits dire... More Details

A wall-mounted axial fan is a propeller fan fitted into an opening in an outer wall or partition, usually carried on a mounting plate or square frame. These fans are expected to re... More Details

A duct axial fan consists of a propeller and the motor carrying it, placed inside a cylindrical sheet-metal casing; the flanges at both ends of the casing turn the fan into an inte... More Details

A vane axial fan carries fixed guide vanes inside its cylindrical casing, placed directly behind or in front of the impeller. Air leaves the impeller with a swirl; the stationary v... More Details

A reversible axial fan can move air in both directions with the same impeller. The blade profile is symmetrical or designed to work in both directions; when the motor's direction o... More Details

A mixed flow fan sits between the axial and the centrifugal fan. Air enters the impeller axially, is directed both forward and outward as it passes over blades mounted on a conical... More Details

A backward-curved fan is a centrifugal fan whose blades are inclined against the direction of rotation. The blades may be flat plate (backward-inclined), curved or of aerofoil sect... More Details

A forward-curved fan is recognised by the many short, shallow blades arranged around the rim of its wheel; the blade tips are bent towards the direction of rotation. This design mo... More Details

A tangential (cross-flow) fan is easy to tell apart from other fans by its wheel, which looks like a long cylinder: air enters on one side of the wheel, passes through the row of b... More Details

An air handling unit (AHU) filters outdoor and return air inside a casing, heats or cools it, humidifies it when needed and distributes it through the building; the supply and exha... More Details

A shrink wrapping machine encloses a product or a group of products in heat-shrinkable film: the film is first placed around the product and sealed, then the pack passes through a ... More Details

In a bread or biscuit plant the oven gets its heat from a burner or heating elements, but the belt that carries dough inside, the fans that move hot air and the turntable that spin... More Details

In a machine that roasts hazelnuts, peanuts, chickpeas or coffee beans, the heat comes from a burner or heating elements; turning, cooling and smoke extraction are handled by sever... More Details

Fruit and vegetable markets, dairy and meat plants, bakeries and logistics centres reuse plastic crates, trays and pallet carriers many times; after every trip they pass through a ... More Details

When the fan motor of an air handling unit is replaced, the new motor must match not only in power and speed but also work with the existing fan's mechanical connection and with th... More Details

To replace a burnt-out motor on an axial fan, fit a motor with the same power, the same number of poles, the same shaft diameter and length, and suitable for the same mounting orie... More Details
