Mobile blast pot or complete blasting trailer? How to compare two quotations
Compare compressed air, hose runs, media handling and site setup before choosing a mobile blast pot or an SB-500 Trailer for contract work.

In short
A wheeled blast pot can be a sound purchase for a contractor who already has a suitable compressor, air treatment and transport. If you take jobs at customers’ premises, price the whole working setup. The SB-500 Trailer puts the blast unit, diesel compressor and air treatment on one trailer. The buying decision turns on what your crew will have to bring, connect and pack away on each job.
Give both suppliers the same job to quote for
Take a real enquiry, such as stripping a coating from timber beams in a building where the trailer must stay in the yard. Sketch the route to the furthest beam. Include turns and stairs. Tell each supplier which coating needs to come off, how you will judge the finish and whether the customer can supply water. Ask for a demonstration on a representative piece.
What belongs on the comparison sheet?
| Item | Separate blast pot | SB-500 Trailer |
|---|---|---|
| Compressed air | Identify the compressor you will use or hire. Check delivered airflow at working pressure for the proposed nozzle. | The diesel compressor travels with the blast unit. Confirm the nozzle and hose combination for your job. |
| Air treatment | List the drying or separation equipment and the connections between units. | Air treatment is part of the trailer setup. Ask to see the air path and routine checks at handover. |
| Hose and handling | Allow for hose, couplings, loading space and a way to collect the hose at the end of the shift. | Specify the hose length, storage chests and whether the quotation includes a powered reel. |
| Media and water | Check which media the pot can meter and what water connection the proposed method needs. | Choose soda or another compatible medium to suit the sample. Confirm the water arrangement for wet work. |
Count the hours around the blasting
Write down the time from collecting hired equipment to starting the first test patch. At the other end of the day, include clearing the work area, winding the hose and returning the compressor. A contractor who already owns the equipment and keeps it on one site will arrive at a different comparison from a mobile operator moving between three customers.
Ask each supplier for an itemised quotation against your list. Put fuel, media, travel and site labour on a separate job sheet so you can see what changes with each booking. If a second person joins you, decide whether they will relieve the nozzle operator, move equipment or handle the next work area.
What to take to a demonstration
Bring your sample, hose-route sketch and both equipment lists. Watch the operator change from the test patch to a full working pass, then see how the hose and accessories are stowed. Review the SB-500 Trailer configuration and ask us to match the demonstration to a job you expect to win.
