JMS M-Series dust collectors offer flexible air intake options from 6m³/s to 60m³/s which means units can be matched exactly to your requirements. High efficiency filters optimise air flow, are energy efficient, and undergo rigorous performance testing to certify a collection efficiency of 99.99% at 0.067 micron.
Mobility Options. Customised to suit site access and application.
Track
Grydale hold international patents for manufacturing the only self propelled, mobile dust collector on the market. Track units offer full mobility with variable speeds between 1-3mph (2-4kph) to increase the speed and efficiency of operations. A key feature is the tracks are hydraulically driven by the diesel engine and operated via remote control. Track mobility allows dust collection units to move and operate alongside dust generating activities, reducing the volume of air requiring treatment and improving the efficiency of whole site operations.
Hydraulic Stepping System
The Hydraulic Stepping System is another key feature and powers four legs that lift the units up, while a pair of skates help to move the unit forward /backwards. Movement can be repeated to achieve the desired travel distance.
Drag Skid
Dust collectors mounted on a skid base offer a cost-effective option. The skid can be dragged using the four towing points at each end of the machine or moved by crane using the four lifting lugs.
Castor Wheel Base
Mobile Dust collectors mounted on a castor wheel base can be moved easily using one of the two available options:
- Sliding – the dust collector key features are the compressed rigid castor wheels to allow ease of movement.
- Lifting – the dust collector also has four designated lifting lugs at each corner of the machine allowing units to be lifted into position.
Castor wheels can be supplied with or without brakes and customised to fit platform rails if required.

Filtration. NATA certified dust collection efficiency of 99.99% at 0.067 micron.
Air Intake
JMS M-Series mobile dust collectors offer flexible intake options which means they can be used for general ventilation and dust extraction at the source. Single air intakes are best suited for large dust loads whilst dual and multiple air intakes can be used to extract dust from multiple sources simultaneously. Flexible couplings allow the dust collector inlet to connect effectively to ducting on uneven surfaces.
Filters
Another key feature of the mobile dust collectors rang is the high efficiency filter cartridges which provide filtration of both dust and diesel particulates. Baffle plates distribute air throughout the dust collector ensuring an even wear of filters. Filter access doors offer easy access to the filters, enabling efficient filter maintenance and maximising machine uptimes.
Filtration Efficiency
Independent, NATA certified Air Flow Performance and Filtration Testing has been conducted both above and below ground as part of rigorous Performance Verification and Certification processes and shows a collection efficiency of 99.99% at 0.067 micron.
Filter Maintenance
The filters can be easily accessed through the filter access doors to allow efficient filter maintenance to maximise machine uptimes. Changing the filters at the optimum time ensures the dust collector does not draw more kW than required to maintain air flows.
Reverse Pulse Cleaning System
JMS M-Series dust collectors have either a plant air connection or an on-board air compressor and receiver tank which feed the pneumatic system to provide reverse pulse filter cleaning. The pneumatic system’s primary function is to clean out the filters during operation to prevent dust build up on the filters.
Pressure and frequency of pulse cleaning is adjustable and helps reduce the number of filter changes required.
Drop Out Box
Our patented drop out box takes heavy dust particles and shotcrete fibres out of the air stream and discharges them through the augers and rotary valves before they hit the filters. This exclusive patented design extends filter life and allows the units to handle extreme dust loading.
Centrifugal Fan. Optimised air flow, energy efficiency and enhanced durability.
JMS M-Series Dust Collectors feature a centrifugal fan that is optimised for the application air flow and pressure requirements. Centrifugal fans offer superior energy efficiency and enhanced durability, allowing them to operate in even the most corrosive environment. One motor and one impellor are used to develop system pressure.
Variable Speed Drive & Velocity Probe
One of the key aspects of JMS M-Series Dust Collectors is the inclusion of a Variable Speed Drive (VSD) as part of the standard configuration. The VSD is used in conjunction with a high precision Air Velocity Probe to allow power consumption to be regulated to achieve the air volume required. This makes the units power efficient and allows power consumption to be reduced by up to 40%.
Fan Silencer
Exhausted air passes through curved silencers to reduce noise pollution. Units can be supplied with a square to round attachment allowing a vent bag to be attached to the exhaust side if required.
Custom exhaust silencers can be designed and manufactured to meet site acoustic requirements.
Dust Discharge System. Hydraulic powered reversible augers maximise dust discharge efficiency.
Hydraulic Reversible Augers Rotary Valves
JMS M-Series dust collectors include hydraulic reversible auger(s) and stainless steel rotary valve(s) dust discharge system to discharge dust particles to the site floor or 1T bulker bags.
The use of hydraulics to power the auger(s) and rotary valve(s) maximises their efficiency whilst the ability to reverse the auger(s) and force material through the clean out hatches is key to increasing uptime in the event of product build up in the hopper and auger(s). This reduces the maintenance effort and the requirement to have LV and HV electricians servicing a mechanical component.
There are a number of dust discharge configuration options including:
Dust Discharge Options
Incline augers
Front or side incline augers allow dust particles to be discharged to 1T bulker bags.
Slurry augers
Available on our JMS 40 M-Series, JMS 50 M-Series and JMS 60 M-Series
Dust can be discharged into a slurry auger by the stainless-steel rotary valve and turned into a wet slurry before being discharged to the site floor. This helps to prevent dust reforming.
The slurry auger can be run off either plant water. If plant water supply is not attached the machine will discharge material as dust but will not affect operation until the water supply can be restored.
Shotcrete drop out box
Available on our JMS 40 M-Series, JMS 50 M-Series and JMS 60 M-Series
The patented drop out box removes shotcrete and heavier particles from the airstream prior to entering the main filter house chamber and auger system. An additional shotcrete auger can be added to further protect the filters whilst reducing the likelihood of a blockage in the main discharge augers.
Control and Monitoring Options. Proprietary software facilitates ease and speed of operation.
PLC (Programmable Logic Computer)
A simple one button start-up / shut-down sequence starts / stops all critical components in a programmed order which increases the efficiency of the unit and provides additional safety for workers. The touch-screen display facilitates ease of operation. On-screen instructions and warnings display error codes which provide a powerful diagnostic tool to support service and maintenance staff.
Our proprietary software is designed to enable performance and trend monitoring. This offers extensive possibilities for system optimisation, process analysis and transparency in machine monitoring, along with scheduling preventative maintenance and servicing at optimum times.
The dust collectors can be configured to record a full dataset including fan hours, filter life, differential and static pressures, hydraulic pressures, emissions, power usage and more.
CANbus
The CANbus system enhances speed, flexibility, and reliability in communication along with supporting effective troubleshooting and maintenance from off-site. The system retains key alarm logs so that system performance and troubleshooting can be undertaken as required.
Key instruments that use the CANbus system include:
Air Flow Meter
An air flow meter monitors the air flow from the exhaust.
Real Time Emissions Monitoring
Real time particle detectors examine emissions coming out of the clean air exhaust and can be tuned to meet the requirements of any given site. The unit can be programmed to alarm when levels are being approached and exceeded.
Differential and Static Pressure Gauges
The static pressure monitor alerts the operator if it is necessary to turn the system volume up due to a long duct run or if there’s a blockage in the ducting. The differential pressure monitor alerts the operator if filters are blocked or if there are higher than normal dust loads.
Central Automatic Greasing System
Grease banks are fitted as standard to all units.
An automatic greasing system can be fitted as an optional upgrade to ensure all bearings are maintained at correct intervals, extending operational life and reducing the time required at service periods.
Fuel Level Indicator Lights (on Diesel Models)
On diesel units, fuel level indicator lights alert the operator to remaining fuel levels.
Proximity Sensors
On track units, proximity sensors can be added to alert the operator when any object becomes close to the unit when moving.
Safety Features. Maximising the health and safety of workers.
JMS M-Series Dust Collectors offer a number of features that focus on maximising the health and safety of workers along with providing a safe working environment by controlling dust and fumes.
Key safety features include:
Emergency Stop Lanyard System
Emergency stop buttons are located on the unit. Track and hydraulic stepping systems also feature a safety lanyard system runs around the perimeter of the unit enabling anyone to ‘grab and kill’ the machine with immediate effect.
Split Starter and Battery Isolators
Split starter and battery isolators allow the use of service lights when the engine is off or being maintained. It also allows access to full machine diagnostics, reducing the risk to service and maintenance staff.
Operation & Maintenance Lights
Operational and maintenance lights have been fitted in key locations on the unit giving operators and maintenance workers clear visibility of components and / or to illuminate working spaces.
Fire Suppression System
To be compliant with country and industry specific regulations, a fire suppression system can be added to units to surround the diesel engine or a chemical suppression system can be added to electric units.
