Ecogate blast gate


1024 846 ESI


Ecogate’s patented system saves customers 68% on their dust collection system electricity costs on average.

This is done by monitoring and understanding what your machines are doing at all times, and adjusting the ventilation system so that it perfectly matches your needs in realtime.

Ecogate sensor
Ecogate blast gate

A sensor is attached to each workstation. When a workstation is in use, its sensor reports this to the greenBOX control unit. The greenBOX opens blast gates to active workstations, and closes blast gates to inactive ones. The reduced air volume requirements let the Power Master Variable Frequency Driver slow down the system fan, which decreases the fan’s power consumption.

  • Lower electricity use
  • Capital Expense Avoidance
  • Analytics
  • Measure & maintain transport velocities
  • Reduced noise
  • Reduced maintenance, increased filter life

Wood Chipper Shredders

Wood Chipper Shredders

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.

Cyclone-Unit-Only Dust Collectors

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.



  • Sizes from 930 cfm to 42 000 cfm
  • Heavy gauge construction
  • Optional wear resistant plate
  • One piece all-welded steel construction

Cyclone-Design High Dust Collection Systems

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.
