Shot-blast cabinets: document media history and dust collection

A blast cabinet's sale description should explain what has been through it. The abrasive media, workpieces and coatings can affect what remains in the cabinet and dust collector. An empty-looking hopper does not answer those questions.
Give the buyer and any removal contractor the history you know. Where records are missing, say which parts are unknown. A fresh coat of paint on the cabinet should not make that uncertainty disappear.
Begin with the last work, then look further back
Ask the operator or production manager about the most recent work and any different earlier uses. Useful questions include:
- What materials and components were blasted?
- Were coatings, scale or other surface materials removed?
- Which abrasive media were used, and are product details available?
- Did the cabinet serve one process or several?
- When was it last used, and what happened afterwards?
- What is known about material remaining in the cabinet, recovery system or collector?
- Are there relevant maintenance, cleaning or specialist assessment records?
- Has anyone changed the extraction arrangement since those records were produced?
Answers should describe facts and their sources. "Operator reports steel castings only during their employment" is narrower than "only ever used on steel". Keep that distinction when older history is unavailable.
HSE's guidance for blasting small and medium castings in extracted cabinets discusses dust arising from the work and the importance of the extraction system. Its specific setting is foundry work in Great Britain. It supports asking about process history; it does not identify the hazards in every used cabinet.
Define the cabinet and collector package
The cabinet may have a dedicated dust collector, a media recovery unit or a connection to shared extraction. Establish which arrangement is present before advertising a complete system.
| Part of the offer | Details to record | Question to resolve |
|---|---|---|
| Cabinet | Identity, working-space dimensions from documentation, access arrangement and visible condition | Does the description match this model? |
| Media system | Identified components and documented media history | Which components are included? |
| Dust collector | Make, model, filter information and location | Dedicated to this cabinet or shared? |
| Ducting and connections | Photographs and agreed sale boundary | Who will specify and carry out separation? |
| Records | Dated maintenance and examination reports | Do they cover the current arrangement? |
| Residual material | Known contents and any specialist assessment | Who will assess and manage it before movement? |
The welding-extraction sale guide explains the broader problem of separating equipment from a shared ventilation installation. A collector beside a cabinet is not automatically owned by the same business or included in the same lot.
Decide what needs attention before listing
Keep three decisions separate: whether the cabinet is suitable for sale, what work is needed before collection, and whether a buyer can use it for a new process. These may require different specialists.
Ask the contractor what information is needed to assess residual material, filters and accessible contamination. Request a written scope for any required preparation and a clear completion record. This guide does not provide a cleaning method or establish that a cabinet is safe to move.
Historic extraction records can help explain condition and modifications. They should not become a claim that a relocated system is approved for a buyer's premises.
If the workshop also has a spray booth, identify each process separately. Combining both under "finishing equipment" can hide very different histories. Apply the same ownership and residue questions to a parts washer supplied under a service arrangement.
Write a useful condition note
For example, a hypothetical description could say: "Cabinet and identified collector offered together. Last recorded use involved the materials listed in the attached history. Earlier use is unconfirmed. Preparation and collection scope subject to specialist assessment." Attach the actual history and resolve the scope before agreeing collection terms.
UK Auction Group can discuss the sale once the equipment boundary and known history are clear. Send those details with photographs and available reports.
