- Motor power
- 4 kW
- Conveying hose ID
- 32 / 38 mm
How it works & where it is used
The GZ-1.5ER is a wheeled electric rotor gunning machine. Despite the model designation, its product page publishes an output range of 0.7–3 m³/h, obtained through rotor selection and variable-frequency control. A pre-dampening nozzle wets material near the application point. The technical table lists horizontal and vertical conveying distances separately.
Steel plant refractory installation and furnace lining maintenance.
Designed around the material flow
- Interchangeable rotor sizes and variable-frequency feed control.
- ABB inverter identified in the published configuration.
- Bag cutter and high hopper with vibrator.
- Dust collection system and lightweight nozzle.
- Heavy-duty solid wheels and blast hose.
- Alternative couplings and a pneumatic version are mentioned.
Rotor selection helps match the feed rate to smaller repair areas or broader installation work. Wheels assist repositioning on a suitable surface. The term mobile does not mean hand-portable: the listed weight is 660 kg and mechanical handling must be planned.
Structure & installation
Installation planning: Confirm compressor delivery, hose routing, nozzle water supply and drive requirements. Conveying distances depend on the actual installation.
Pending confirmation. A model-specific installation drawing, interface dimensions and electrical diagram have not been supplied. Request these for the offered configuration. Product photographs do not replace installation drawings.

Air, power & conveying boundaries
Air-pressure values describe the pneumatic system, not the pressure of a hydraulic pump. Do not assume maximum output and maximum conveying distance can be achieved simultaneously.
Information needed for selection Provide the target output and full hose route, including elevation and bends. Confirm the exact rotor, electrical supply and lifting arrangement. No numerical rebound reduction is adopted from the marketing copy.
Pending confirmation. A verified performance curve or material trial record is not available. Maximum values must not be assumed to occur simultaneously.
Configuration & maintenance
Items requiring confirmation The listed rotor speed is 7 rpm while the description states variable-frequency control; request the available speed range and rotor selection. Horizontal and vertical limits are not simultaneous route guarantees. Electrical voltage is not stated in this table.
Pending confirmation. Confirm the standard accessory list, consumable parts and operating instructions for the exact build. Confirm the hose diameter, hose length, nozzle and whether a water pump is included.
Documentation & evidence
Pending confirmation. No model-specific independent test report or verified project case has been supplied for this representative page. Product certification applicability, document validity and public display permission remain to be checked. No certification or service-life guarantee is implied.
Quotation & support scope
Packaging, minimum order quantity and lead time: Not established in the cited technical data. Request the packing method, packed dimensions, gross weight, order quantity and delivery schedule in the quotation. Machine dimensions and weight are not shipping measurements.
Also confirm the standard accessory list, consumable parts, warranty, commissioning support, packing, MOQ and lead time. No certification, factory production capacity or quantified service-life claim is added without supporting records.
