Fans

Forward curve centrifugal fans and blowers are suitable for applications requiring high air volumes with low to medium pressure requirements. Currently the most pervasive fans in the market, many residential and commercial Air Handling Units (AHU) are fitted with Torin, Lau Industries, Yilida, Muller and Trane direct drive and belt drive blowers, which can all be sourced through Markair.

Forward curve fans are also well suited to many industrial applications, including cooling towers, conveyor systems, refrigerated dock seals, processing fans and light materials handling. Markair is Australia’s last manufacturer of many of the forward curve fans in the market currently.

Replacement wheels for Torin, Nicotra and Kruger direct drive fan decks and belt drive blowers. These wheels are authorised replacement components for many OEM applications including Brivis, Braemar, Temperzone and Carrier and units. We also manufacture replacement fan wheels up to 1000mm in galvanised and 316 stainless steel for Cooling Tower applications, as well as the hand built Gammut series wheels (from 4” to 15”) in galvanised and 316 stainless steel for smaller applications.

Backward curve blowers suit applications with high volume and medium to high pressure requirements. Highly efficient, many of our ebm-papst and Ziehl-Abegg fans are EC controlled, representing the latest technology available in the market for minimising power consumption. With full sheetmetal engineering capabilities in our production facility, Markair can provide all the custom designed boxes and filtration systems that may be required to house the fans, meaning a complete solution for our customers.

Axial fans are best suited to applications where high air volumes and low pressures are required. We supply the complete range of ebm-papst and Ziehl-Abegg AC and EC axial fans for condensing units and large scale AHU retrofitting, as well as inline duct mounted fans for residential, commercial and industrial applications, including Ex’e’ and Ex’d’ rated systems for spray booths and oil rigs.

Suitable for light and heavy duty exhaust applications, our range of roof units can be constructed to suit many commercial kitchen exhaust applications, as well as industrial facility and warehouse ventilation.

Radial fans are capable of light and heavy materials conveying, as well as for applications with very high pressure requirements. Markair fabricates and balances radial blades of all different sizes in house, with blades constructed in mild steel and 316 stainless steel. Our G300 and G450 direct drive and belt drive high pressure blowers have been a mainstay in the market for many years as a versatile high pressure airflow delivery system.

Our fully equipped sheet metal fabrication facilities include heavy duty rollers, folders, welders and guillotines, as well as a state of the art AMADA laser machine to facilitate the production of anything our customers require, be it large scale manufacture or an economical small run. Our fabrication engineers have decades of experience building duct systems, duct transitions, guards, attenuators as well as square and round industrial silencers. We work with specialist filtration experts to incorporate HEPA filters for hospitals and other sensitive applications.

We can also build frames and bases in house for our plug fans and forward curve blowers, incorporating motors and drives as a complete solution for our clients.

As a components wholesaler to the HVAC industry, Markair has partnerships with many suppliers to provide many ancillary products, including single phase speed controllers, variable speed drives (VSDs) and soft starters, V-Belts, taper lock bushings, bearings and motor brackets for Torin, Lau and Kruger direct drive fan decks.

Markair can also manufacture replacement imperial and metric shafts with our precision tooling, from 19mm to 4” hollow bar, with the inclusion of keyways as required. Materials used include 1030 precision ground mild steel shaft and centreless ground 316 stainless steel solid shaft (up to 60mm).

With our Amada 3KW laser cutter on site and the latest CAD and CAM software, we can design and cut anything we can draw in 2 dimensions in many materials, up to 5mm thick.
