Paper waste — printing
Extraction for printing lines so trim and offcuts leave the press instead of piling up on the floor.
Engineering portfolio
Industrial ventilation engineering for real plants
CJ Dustraction designs and specifies the systems that pull waste, dust and fumes out of real plants — paper, print, welding, spray booths, silos and wood shops — then our workshop builds and installs the kit that makes the drawings work on the floor.

How the engineering side works
When a factory needs more than a catalogue fan, CJ Dustraction sizes the airflow, selects the separators, and lays out the duct runs so scrap and fumes leave the line without choking the process.
We design and specify paper and trim waste systems, welding fume capture, spray booth ventilation, general plant air, sound enclosures, agricultural silo aeration and saw-dust extraction for Cape Town and wider South African plants — then our Blackheath workshop fabricates and installs what the drawings call for.
What you get
- Practical system layouts matched to how your plant actually runs
- Choice of mechanical separators or cyclones (cyclonics up to about 95% @ 10 microns)
- Chopper and booster fans from size 7 through the large size 45 range
- Fabrication and installation backed by CJ Dustraction’s Blackheath workshop
Engineering services
Ten core offerings from the industrial ventilation portfolio — designed for printing, paper, metalwork, wood and agri plants.
Paper waste — paper industry
Heavier paper and board scrap systems with mechanical separators or cyclones into compactors.
Trim waste extraction
Edge-trim suction designed for paper and printing applications across RSA plants.
Chopper & booster fans
Complete fan range from size 7 to the large size 45 units for paper and print waste conveying.
General ventilation
Factories, warehouses, generator rooms and cooling-tower exhaust stacks.
Ventilated sound enclosures
Sound suppression around noisy plant while keeping airflow under control.
Paint spray booth ventilation
Booths and custom ventilation for furniture and heavy engineering spray work.
Welding fume extraction
Push-pull systems, arms and reverse-pulse filters for auto, heavy eng and welding schools.
Agricultural / silo aeration
Ventilation and aeration layouts for grain and bulk storage silos.
Saw dust extraction
Custom wood-chip and shaving systems with cyclones, after-filters and purpose-built fans.
Project gallery
Selected installs and layouts from the engineering presentation — captions kept close to the original notes.
Paper waste extraction systems
Mechanical separators or cyclones — pick what fits the fibre and the footprint. Outdoor plant feeding blue hoppers into compactors keeps the print hall clear.
Reverse-pulse after filters — CTP Printers, Cape Town
Tall reverse-pulse filter banks after the primary separators, with caged ladder access and large inlet ducting from the production hall.
Trim waste extraction
Trim waste removal systems manufactured and installed throughout RSA for the paper and printing industry — designed around the machine that makes the scrap.
Typical paper waste layout
Mechanical air separators feeding balers or compactors. Cyclonic separators are also available — maximum efficiency around 95% at 10 microns.
Chopper and booster fans
A complete range from size 7 to the giant size 45 fan for paper and printing waste conveying — engineered drawings before steel is cut.
General ventilation
Factories, warehouses, generator rooms and exhausts, and cooling-tower exhaust stacks — ducted systems sized for the heat and air changes you actually need.
Ventilated sound enclosures
Sound suppression for noisy machines — extract ducts, axial fans and cylindrical attenuators designed so silencing does not smother the airflow.
Paint spray booth ventilation
Spray booths built to client specification, with ventilation tailored for furniture and heavy engineering coating work.
Enclosed spray booths
Full enclosures with filter banks and observation glazing — clean spray environments without drifting overspray into the rest of the shop.
Welding fume extraction
Push-pull systems for automotive plants (including Pretoria), articulated arms at the bench, and fully automated reverse-pulse filters for welding fume dust. Suited to auto, heavy engineering and welding schools — manual or automatic.
Workshop fume layouts
Multi-station welding halls planned with overhead ducting and external fan units so each bay gets capture without fighting the next.
Agricultural ventilation & silo aeration
External duct runs and aeration branches along bulk storage silos — keeping grain and product conditioned in storage.
Silo blower packages
Centrifugal blowers and vertical ducts on corrugated silos — simple, rugged aeration that survives outdoor duty.
Saw dust & cyclone separation
Custom saw-dust systems using cyclonic separators and after-filters, with ducting and fans built to handle chips and shavings — installed by skilled teams.
