Blast cabinets

Clemco cabinets — a controlled process in a closed system

Clemco cabinets are designed for precision cleaning, matting, roughening, oxide, burr and coating removal, and finishing of small and medium-sized workpieces. The operator remains outside the blasting zone and handles the part through sealed gloves, while negative pressure, the cyclone and the filter unit retain dust and return reusable abrasive to the process.

SURFACE can provide compact Pulsar cabinets, modular BNP systems, suction or pressure configurations, and automatic or fully custom-developed cabinets. Selection depends on the material and geometry of the part, required capacity and finish, abrasive type and available compressed air.

Robust construction, a matched cyclone and filter, genuine wear parts, safety interlocks and long-term spare-parts availability make Clemco cabinets dependable equipment for daily industrial production.

Clemco cabinet dimensions

Correct selection requires more than the external cabinet dimensions. The working envelope, clear door opening and space for the complete system must be checked: cabinet, trolley or turntable, cyclone, filter, pressure vessel and safe operator access.

• Kit-Cab and Pulsar II suit smaller processes with a small installation footprint and straightforward handling.
• Pulsar III, VI and VIII, and BNP 65 and 220, provide a choice between compact and modular layouts.
• BNP 601 and BNP 721 offer working envelopes up to 1,820 × 1,750 × 1,830 mm before a special cabinet or blast room is required.

Pulsar — a complete compact unit

Pulsar models are intended for users who want a complete solution with a small space requirement. The integrated cyclone separates dust, broken-down abrasive and contamination from reusable media, while the filter unit maintains visibility and negative pressure. Options include turntables, trolleys, additional lighting and other accessories.

BNP — maximum flexibility

Separating the work chamber from the cyclone, pressure vessel and filter lets a BNP system adapt to the available space and process. The filter may be installed away from the immediate work area, while heavy parts are loaded by trolley or turntable. BNP 721 handles larger components without requiring a complete blast room.

Cabinets for plastic media, wet blasting and industrial soda

The chamber, metering, cyclone, pipework, seals and filtration must be matched to the specific medium. These processes are not treated as a simple abrasive substitution in a standard cabinet.

BNP suction guns, automatic guns, nozzles and ZERO gloves

These are not generic accessories. Every component is selected for the cabinet type, abrasive, pressure, available airflow and required capacity.

Automatic Clemco guns

Fixed or moving suction and pressure assemblies can be installed in multiple positions. Gun quantity, diameter, angle, oscillation and path are defined around the workpiece and cycle.

Automation and repeatable results

Automatic cabinets may use indexing or rotary tables, multiple suction or pressure nozzles, oscillation, automatic doors, manipulators and PLC/HMI control. Gun position, movement speed, part rotation, cycle time, abrasive separation and filtration are engineered as one process rather than assembled from unrelated elements.

Ventilation, filtration, safety and the working environment

The cabinet and its filter unit operate as a matched negative-pressure ventilation system. Required airflow is determined by chamber size, media, dust quantity and operating intensity. Correctly controlled airflow maintains visibility, prevents dust escaping into the workshop and carries fine particles reliably to the filter. A safety interlock immediately stops the blast stream if a door opens.

Filter cartridges in the Clemco configurations offered by SURFACE are aluminium-coated and BIA-certified. Pulse cleaning maintains stable negative pressure, and a suitable filter unit can achieve dust concentration in cleaned air of up to 1 mg/m³. Higher dust loads require PLUS configurations, additional filter area or a separate industrial ventilation unit.

Genuine cabinet parts

Available parts include gloves, rings, viewing windows and protective films, BNP suction-gun assemblies, SG-300 and other suction guns, pressure nozzles, air jets, holders, abrasive hoses, corrugated transport hoses, cyclone parts, filter cartridges, seals and electrical safety components. SURFACE provides identification, supply and service as required in Serbia and the region.

Typical applications

Precision cleaning, removal of oxides and burrs, matting, roughening before bonding or coating, shot peening and finishing of parts in aerospace, automotive, medical, toolmaking, mechanical engineering and other industries.
