Chip can be blown 10m vertically and 4m sideways which is a good distance, delivery rates of 1 cubic metre a minute are possible. This may not sound very quick but very often the alternatives are far more time and energy consuming. Chip can be sucked up with a flexible pick-up hose with a length of up to 4m, although over 3m suctions starts to be reduced. 

Auer Wood Chip Blowers

With the biomass energy and chip/pellet heating industry finally gaining real momentum, more and more companies and customers are being forced to look at the logisitics of moving volumes of woodchip and pellets. Where access with tipping trailers is possible this presents little or no problem but where access is limited or impossible by a vehicle then chip blowing systems are a viable way forward. Working with our partner Auer we are able to deliver PTO, Hydraulic and 3 Phase Electrically driven chip blowing systems.

Auer Blower

How much woodchip will it move?

There are many variables such as chip size, moisture content, distance etc, but the blower is capable of moving approximately 1m3 per minute.

How much chip will the Auger hopper hold?

The Auger Hopper holds approximately 2m3.

How far will it blow chip?

The blowers are capable of moving chip either 4m vertical and 10m horizontal or 10m vertical and 4m horizontal.

Is there a Single phase Electric Motor Option?


What is the smalleset 3 Phase Motor?

9 kilowatt.

What 3 Phase Electric Supply do I need?

You will need a 35amp supply with a C or D rated trip. Constant current consumption 28amps.

How noisy are the Blowers?

80 to 92 dBA, this can be greatly reduced by creating a housing around the blower.

What does the discharge pipe consist of?

The discharge pipe is in metal rigid sections which is held together by clamps.
Bends are negociated by 4 rigid sections available in 30deg, 45deg and 90deg bends.

Can you have flexible discharge pipes?

No this is not recommended unless you have smooth connections.

How big are the discharge and infeed pipes?

250mm or 10".

Can you use smaller diameter suction and discharge pipes?


Does the use of a cyclone reduce delivery rates?

Yes a 20% to 30% reduction in delivery.
