The Smallaire FUMIGATION SYSTEM is designed to vent air through silos and is required to be recirculated from the bottom of the silo through to the top of the silo and back to the 80 LPS fan.

No more placing phosphine tablets directly into the grain source, with the use of the Fumigator the tablets are placed in the tray provided and once the tablets are spent the powder form drops through the mesh grate ready for a mess free disposal also no residue left in the grain.

The Smallaire Fumigation System includes two key components:

1. Phosbox® Inline Fumigator Box

2. Bunker Tarpfast

Tarpfast your Bunker this season

The Tarpfast blower works by creating a negative pressure under bunker tarps there- fore sucking the tarp to the grain, this stops the tarp from flapping and tearing in windy conditions savings on grain spoilage, costly tarp repairs and down labour time.

Can you afford NOT to have a Smallaire Tarpfast on your bunkers this season?

Do the Math…

  • Torn Tarps
  • Spoilt Grain
  • Labour Costs
  • Down Time
  • Dangerous conditions
  • Peace of mind

“I would highly recommend the Smallair tarpfast. After having used these units for several years at Moore Bulk Storage Horsham, we have found that our tarps last longer and suffer no ripping or ballooning in windy conditions. I believe these units have prevented any tarp losses in server winds.
The other benefits of these units are, compact 
design and low power consumption, with a 1/3 horse power motor capable of holding a 10,000 tonne bunker tarp. Brett Moore – Moore Bulk Haulage
