General Infomation

Many manufacturers will state the volume of air required for each machine in their manual. If

not, note the size of the extraction port and use the chart below

outlet size

100

125

150

200

Example: for a single machine with a 100mm port an extractor of a minimum of 700m³/hr

will be suffi cient. For multiple machines count the number of extraction ports per size, multi-

ply the number of each size by the volume of air required. Then add the results per outlet size

to give you a total volume of air required. This total is for all the machines operating at the

same time. You then must decide which and how many machines will be used at the same

time. Divide the total volume of air required by this number and add 500m³/hr. Choose an

extractor that gives the airﬂ ow required by your calculations. Look at the main inlet size of the

extractor, this is the size of the main duct to be used. In larger systems the ducting should get

larger towards the extraction unit as more machines that are in use are added to maintain the

correct air speed in the duct. This is very important; if the airﬂ ow is too low a build up of dust

and debris will occur and is a fi re and explosion risk. If the air speed is high then the system

will be noisy but there will be no deposits in the ducting. Always use blastgates to close off

airﬂ ow to machines that are not in use.

Basic Maintenance

WARNING! ALWAYS WEAR A DUST MASK

WARNING! ALWAYS WEAR EYE PROTECTION

Daily

• Empty the collection bag before it overﬂows, wear a dust mask

whilst removing and emptying the bag.

Weekly

• Check the inlet and outlet duct and remove any accumulated

sawdust.

•Check the inlet hoses for splits and cracks, repair as necessary.

• Check the dust collection bag for wear and tear, especially

around the neck of the retaining belt. If wear or fraying is

occurring, replace the bag.

• Check the motor for dust, sawdust, shavings etc, build up. If

this has occurred, clean with a vacuum cleaner, see fi g 22.

• Move the shaker paddle handle back and forth to remove any

built up dust and debris from inside the fi lter.

Monthly

• Remove the ﬁlter securing belts (5) and remove the ﬁlter

assembly (2), see fi g 23-24. Using an 'M' class vacuum cleaner,

clean inside the fi lter.

Basic design

• Keep it simple, don't over complicate the system.

• Keep it straight, ducting runs should all be straight with as few bends as possible.

• Keep transfer duct as big as required by the extractor, this should get larger towards the

extractor.

• Keep ﬂexible duct to a minimum. If the machine cannot be connected to the system by

solid ducting only then should ﬂ exible ducting be used for the fi nal connection.

• Keep branches joining the duct to a maximum of 45° When branches join the main duct

ideally they must enter at the side or the top at an angle of a maximum of 45° towards the

direction of ﬂ ow.

• Fit blastgates to maximise efﬁciency and balance the system.

The negative pressure inside the ducting draws air into the system. Incorrect sizing of the

duct, too many bends coupled to lots of ﬂ exible hose induces losses into the system and in

badly designed systems this is akin to leaving the hand brake on in a vehicle.
