Our shredders are built to last. We are high quality wood chipper manufacturers and have received excellent ratings in chipper shredder comparisons.

The MacDonald Steel Mini-Shredder is employed to accept trim waste on a continuous basis from an air-conveyor or belt conveyor or on an intermittent basis as a floor sweep for general clean-up, and reduce the scrap in size for more convenient handling and to improve the baling characteristics of the scrap.

The scrap material is reduced into small pieces in the shredding section consisting of a series of fixed teeth on a rotating arbor which pass through a fixed grating. A V-belt drive is used to run the shredder.

The shredder is statically and dynamically balanced. The arbor shaft is supported by oversized, self-aligning mount bearings. The drive is fully-guarded. A bolted cover provides access to the arbor.

The MacDonald Steel Shredder is employed to reduce scrap in size for more convenient handling and to improve the scraps baling characteristics. The Shredder is constructed of heavy structural members and is all-welded construction.

We are high quality wood chipper manufacturers and have served the wood industry since the 1950’s.

Do you want to purchase vent ducting/fan ducting? Do you want to install system components for loading chutes/hogs? Do you need large round metal ducting?

MacDonald Steel offers a full line of components for a complete pneumatic system. We offer:

We stock a variety of system components for loading chutes/hogs.

MacDonald Steel Reverse Taper load chutes are designed to be used with our rotary air locks. They are used to convey material from the collector/filter unit’s lower cone to the rotary air lock.

MacDonald Steel Rectangular Air Return ducting will reduce heating costs in the winter months and conditioned air in the summer by returning the air back to the building.

An optional air diverter, which is either manual winch operated, or electric actuator type, is available to divert the air to atmosphere in the summer months to allow for good circulation of air in the building when required.

We offer high quality large round metal ducting.

Please contact us for more information on loading chutes/hogs, vent ducting/fan ducting and large round metal ducting for your pneumatic system.

MacDonald Steel manufactures, installs and services our own line of fans. We offer two types of air handling fans, and three types of material handling fans.

We offer two types of air handling fans. One a standard type and the other a high efficiency backward curve deign. The sizes range from 1500 to 160 000 cfm, standard designs of up to 36″ of water.

We also carry three material handling fans, our Hogger Type for heavy material loads or large pieces of waste in the air stream. The Hogger Type is capable of chopping up long pieces of paper in the air stream. We also offer two high efficiency material handling fans designed for moderate material loadings in the air stream The sizes range from 1200 to 160 000 cfm, standard designs of up to 36″ of water.
We offer several options including, spark resistant fans, temperature sensors and motion sensors.

We also offer superior custom exhaust fan design in Canada.

MacDonald Steel designs, manufactures, install’s and services its own fans.

They are built to last. Our state of the art facilities include the latest fabrication and machining equipment to assure a high quality product.

SKF bearings are standard equipment making MacDonald Steel fans a superior product. Our fans are manufactured of heavy plate steel and are continuously welded for extended wear and long life.

Please contact us for information on our exhaust fan design in Canada. Learn about our industrial exhaust fans… corrosion resistant and more!

We design and build our own cyclones.
Our cyclone-unit-only dust collectors meet the highest standards. We install and service cyclone-design high dust collection systems for a variety of applications. Our woodworking cyclone dust collectors deliver high quality air filtration.

The MacDonald Steel Type “HE” (High Efficiency) cyclone/separator is intended to handle a range of fine to coarse dust applications, the selection of the specific cyclone is dependant upon particle size and weight, inlet dust concentration, cyclone height and ratio of the separator body and gas outlet diameters. Generally, efficiency decreases with increasing gas viscosity or density, separator, body diameter, gas outlet diameter and gas inlet area.

MacDonald Steel Type “HE” cyclones/separators feature small diameters and elongated cylinder and cone lengths. The dust particles are separated from the conveying gas by a combination of centrifugal and gravitational forces.

Our cyclone/separator can also be provided with a wear liner on the inlet to reduce body wear when very abrasive materials are being conveyed. All of our liners are made of CHT-100 abrasion resistant material. We also provide a cleanout in the lower cone of each of our cyclones.

MacDonald Steel cyclone/separators are also available with structural support, safety ladders and platforms when purchased as a complete package.

We have served the wood industry since the 1950’s.

Please contact us for information about our cyclone-unit-only dust collectors, including our woodworking cyclone dust collectors. We manufacture and install our cyclone- design high dust collection systems for many applications.
