4.7 BLAST UNIT – CHASSIS
All components on the blast unit are mounted on a mobile transporter. This
transporter consists of a two-wheeled rear chassis with an additional two-
wheeled front caster kit for added stability.
The adjustable operator’s handle connected to the chassis and may be pushed
down to allow the operator to lift the blast seal over small obstructions. For safety
reasons, we recommend that the bottom of the front urethane seal not be lifted
more than approximately 1/8 inch from the surface being cleaned.
Warning: Lifting the seal edge beyond this may allow high
velocity abrasive to escape the blast chamber (See Section 2).
4.8 CLEANING MEDIA (ABRASIVE)
Blastrac provides a variety of specially sized, high quality abrasive for Blastrac
shot blasting systems. This steel abrasive is made of high quality martensitic
steel to provide operating longevity and minimal abrasive breakdown.
The 1-8DEZ is designed to operate with abrasive in sizes S-110 through S-390.
The selection of proper abrasive is very important to the performance of the
Blastrac shot cleaning system.
Your Blastrac representative can help with the
proper selection of abrasive for your particular application.
The steel abrasive causes minimum wear on the internal blast components. The
dust and contaminants are the principal causes of component wear. A well-
maintained ventilation system will minimize abrasive contamination, which helps
reduce operating costs and increases the overall efficiency of the shot-blasting
system.
