Page 4: Scope Of Manual
1 Scope of manual This manual covers operation and maintenance for the following single chamber blast machines with pneumatic or electric remote controls and manually or pneumatically operated media metering valves: Volumina Model Max. pressure [bar] Remote Control Valve Metering valve When using RMS-2000A RMM-50A... -
Page 5: Application And Restrictions
2 Application and restrictions Single chamber blast machines can be used with all types of abrasive (60 – degree conical bottom for fine mesh abrasive on option). Table 1 shows the maximum working pressure for the different models available. Higher working pressure is possible only for special designs. The following options are recommended: −... -
Page 6: How The System Works
Figure 1 shows the major components of the standard blast machine: • Pot with − remote control valve RMS-2000A (RMS 1500+500) or RMM-50A (item 2). − muffler (item 5). − moisture separator (item 4). − media metering valve (item 3) manually or pneumatically operated. −... -

3.2 Blast machine with pneumatically operated media metering valve Figure 2: Blast machine with pneumatically operated metering valve and pneumatic remote controls. Principle of operation: same as the standard pressure blasting device. When the deadman handle (item 6) is depressed the metering valve opens, when it is released, the metering valve closes. -
Page 8: Optional Electric Remote Controls
3.3 Optional electric remote controls Figure 3: Electric remote controls and pneumatically or manually operated abrasive metering valve. In order to reduce the time to stop blasting (especially when using longer blast hoses), the twinline hose between the deadman handle and the remote control valve is replaced by an electric cord (orange) and the electric panel RME-1 (item 15). -
Page 9: Dual Function Pneumatic
3.4.1 Dual function pneumatic An additional 3-way slide valve (pos. 6.1) enables the operator to open or close the metering valve when the deadman handle is depressed. When the slide of the 3-way valve is moved to the left the abrasive metering valve opens, to the right it is closed again. -

3.4.2 Dual function electro-pneumatic Figure 5: Dual function electric. An additional electrical switch on the deadman handle enables the operator to open or close the pneumatically operated metering valve when the deadman handle is depressed. A magnetic valve mounted on the electric control panel RME-2 (item 15) converts the electric signal into a pneumatic signal. - Page 11 Principle of operation: Compressed air is supplied to the system via a HMS water separator (item 4). The air is fed into the RMS 2000 remote control valve (item 2) and from there via the port 2A (brown remote control hose) to the deadman handle (item 6) and to the pressure regulator (1/4"...

Page 16: Daily Set-Up
5.3 Daily set-up Not necessary if an initial installation or reinstallation was performed (see section 5.2). (1) Air supply. Start compressor and bring it up to operating temperature (5 to 10min.). − Abrasive-resistant clothing. (2) Put on protective equipment. − Airfed helmet with connection to breathing air supply (air filter) and adjustment of air volume with an air control valve attached to belt. -
Page 17: Shut-Down
5.5 Shut-down (1) Empty all abrasive. Blast machine not in use > 1 day (abrasive could get moisture). 5.6 Shut-down when moving equipment No special measures required. 6 Maintenance 6.1 General During operation blast machines are exposed to wear. In order to ensure safe operation and high efficiency the blast machines should be maintained according to the following check lists. -
