70 to 500 liters — one unit for every application and work volume
CYM Materiales designs and manufactures a complete line of blast pots for manual abrasive projection by compressed air. With four models ranging from 70 to 500 litres capacity and working pressures up to 10 kg/cm², CY blast pots can project metallic abrasives — carbon steel or stainless steel shot — and mineral abrasives — aluminium oxide, slags, garnet and other alternative abrasives used in sandblasting operations — without any change to the equipment or circuit accessories.
The construction design complies with ASME standards, featuring a semi-elliptical head, conical bottom and a wide inspection port that facilitates maintenance and replacement of the automatic pop-up loading valve. The structure does not rest on the conical bottom, preventing tank deformation under pressure. CY blast pots are manufactured in four control system variants — manual (M), with depressurization (D), dual (DD) and Pinch (P) — adapting to each working condition through easily installed conversion kits.
CYM blast pots operate in naval and industrial blast rooms, in field work and industrial maintenance, and as integrated components in automatic shot blasting and shot peening machines. Universal compatibility with any type of abrasive, the Dead Man active safety system, and the availability of proprietary accessories — hoses, couplings and tungsten carbide or boron carbide Venturi nozzles — make the CY line a complete solution for demanding manual shot blasting operations.
El diseño constructivo responde a la norma ASME, con cabezal semi-elíptico, fondo cónico y boca de inspección amplia que facilita el mantenimiento y el recambio de la válvula de carga automática pop-up. La estructura no apoya en el fondo cónico, evitando deformaciones del tanque bajo presión. Las tolvas CY se fabrican en cuatro variantes de sistema de control —manual (M), con despresurización (D), dual (DD) y Pinch (P)— adaptándose a cada condición de trabajo mediante kits de transformación de fácil montaje.
Las tolvas CYM operan en cuartos de granallado de uso naval e industrial, en trabajos in situ y mantenimiento en campo, y como componentes integrados en equipos automáticos de granallado y shot peening. La compatibilidad con cualquier tipo de abrasivo, el sistema Dead Man de seguridad activa y la disponibilidad de accesorios propios —mangueras, acoples y boquillas Venturi de carburo de tungsteno o carburo de boro— hacen de la línea CY una solución completa para el granallado manual de alta exigencia.
Applications
Uses and shot blasting processes
CYM blast pots adapt to a wide range of industries and processes. Their universal compatibility with metallic and mineral abrasives, combined with the availability of four control systems, allows configuring the exact equipment for each application — from point field work to multi-station blast room installations with simultaneous operators.

INDUSTRIES AND APPLICATIONS
- Blast rooms for structural steel and welded construction
- Naval blasting: hulls, blocks and ship sections
- Oil & gas: blasting of threads, connections and OCTG pipe body
- Tanks, pressure vessels and large industrial structures
- Shot peening integrated in automatic SAT and spring machines
- Industrial maintenance and field work on site

PROCESSES AND ABRASIVES
- Shot blasting with metallic abrasives: carbon steel or stainless shot
- Sandblasting with mineral abrasives: garnet, slags, aluminium oxide
- Surface preparation for shop primer and industrial coating application
- Abrasive blow-off from the same hose without equipment change (DD system)
- High-pressure blasting up to 10 kg/cm² on critical thickness surfaces
- Multi-station configuration with multiple simultaneous operators
REMOTE CONTROL SYSTEMS
What do you need to blast? Find your machine
CY blast pots are manufactured in four abrasive cut-off control system variants, adapted to different working conditions, hose lengths and required safety levels. The modular design allows any basic unit to be upgraded to a remote control system using quick-installation conversion kits.
| Function | M - Manual | D - Remote | DD- Dual | P - Pinch |
|---|---|---|---|---|
| Pressurizing and depressurizing | Manual | Automátic | Automátic | Manual |
| Abrasive metering | Manual | Manual | Manual | Manual |
| Air and abrasive cut-off | No | Yes | Yes | Yes |
| Dead Man control | No | Yes | Yes | Yes |
| Blow-off from same hose | No | No | Yes | No |
| Minimizes cut-off hose wear | No | No | No | Yes |
System description
| Tipe of control | Detail |
|---|---|
| M - Manual Control | For operations where the blasting operator remains in sight of the blast pot operator. The lowest-cost solution for short hose runs. |
| D - Remote Control | Provides the operator with maximum freedom of movement and safety. The Dead Man system stops all projection when the trigger is released. Enables automatic recharge from accumulation silos. |
| DD - Dual Remote Control | Same as D, with the additional function of selecting from the hose end between abrasive projection and compressed air blow-off — ideal for sweeping accumulated abrasive from parts without changing equipment. |
| P - Control Pinch | Double-acting pneumatic pinch valve cut-off. Minimizes hose wear and significantly extends service life. Recommended for high-frequency operation installations. |
