Grydale JMS F-Series. Fixed Dust Collectors
Key Features. JMS F-Series.
Custom Design. Flexible Modular Design.
The Grydale JMS F-Series fixed-unit dust collectors offer a long-term and cost-effective solution to dust and fume control and are designed to handle high-volume dust loads. Our dust collectors consist of a centrifugal fan, dirty air intake, high-efficiency filters, reverse pulse filter cleaning system, dust discharge system, clean air exhaust, and fan silencer.
The JMS F-Series is based on a modular design, which allows for the flexibility to size the dust control units according to the required air volumes. Units range from 6,000m3/hr to 400,000m3/hr. Dust collectors can be combined to provide greater airflow.
Our engineering team can take site and process drawings to determine airflow requirements and design ducting configuration to achieve a total dust control solution.

Air Intakes
JMS F-Series dust collectors can be designed with single or multiple air intake options, depending on the ducting’s design, application, and site conditions.
- Configuration options: Single, dual or multiple air intakes.
Filters
High-efficiency filter cartridges filter both dust and diesel particulates. Baffle plates distribute air throughout the dust collector, ensuring even filter wear.
- Configuration options: The number of filters required depends on the air-to-cloth ratio needed for the specific application.
Filtration Efficiency
Certified air flow performance and filtration testing have been conducted both above and below ground as part of rigorous performance verification and certification processes. The testing shows a collection efficiency of 99.99% at 0.067 microns.
Filter Maintenance
The filters can be easily accessed through the filter access doors, enabling efficient filter maintenance and maximising machine uptime. Filter life is dependent on dust type, dust loading, and application.
Changing the filters at the optimum time ensures that the dust collector draws no more kW than is required to maintain air flows.
Depending on the height of the dust collector, customised maintenance access platforms can be designed and manufactured.
Reverse Pulse Cleaning System
JMS F-Series dust collectors are connected to an external compressor to provide air for the onboard reverse pulse filter cleaning system, which uses the plant air receiver tank and attachment kit fitted to the unit.
Jet tubes direct air inside the filters, blasting air from the inside of each filter, effectively removing dust build-up and preventing the filters from clogging. The adjustable timer allows the pressure and frequency of pulse cleaning to be set to the application and dust loading, reducing the number of filter changes required.
Centrifugal Fan
Centrifugal fans offer superior energy efficiency and enhanced durability, allowing them to operate in even the most corrosive environments. They provide the required air volume using one motor and one impeller to develop system pressure.
- Configuration options: Centrifugal fans are custom-designed to provide optimum air volume and pressure for specific applications. Fans can be ground or roof-mounted depending on the application and space constraints.
Fan Silencer
Exhausted air passes through silencers to reduce noise pollution.
- Configuration options: Custom exhaust silencers can be designed and manufactured to meet site acoustic requirements. An exhaust stack may also be required, depending on the site and application
Dust Discharge System
The hopper collects the heavy dust particulates released from the filters. The dust type will determine the number and shape of the hopper(s).
For standard applications, a pyramid hopper is used, which discharges via a slide gate into a steel recovery bin or bulker bag.
- Configuration options: If collected dust doesn’t ‘flow’, a rotary valve coupled with a pneumatic aerator that automatically cleans the hopper can be installed for more efficient discharge.
For high volumes, a trough hopper can be used with an auger and rotary valve, which can also convey materials to a separate discharge location, for example, onto a conveyor within a processing plant.
Programmable Logic Computer (PLC)
A simple one-button start-up and shut-down sequence starts and stops all critical components in a programmed order, increasing the unit’s efficiency and providing additional safety for workers.
- Configuration option: A touch-button or touch-screen HMI Interface can be added if additional functionality is required.
CANbus System
- Configuration option: A CANbus system enhances communication speed, flexibility, and reliability and supports effective troubleshooting and maintenance from off-site. The system retains key alarm logs so that performance and troubleshooting can be undertaken as required.
Instrumentation
Air Flow Meter
The airflow meter monitors the airflow from the exhaust.
Real-Time Emissions Monitoring
Real-time particle detectors examine emissions coming from 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 approaching and exceeding.
Fan and Differential Pressure Gauges
The fan pressure monitor alerts the operator if the system volume needs to be increased due to a long duct run or a blockage in the ducting.
The differential pressure monitor alerts the operator if filters are blocked or if dust loads are higher than normal.
Safety Features
Grydale JMS F-Series dust collectors offer several features that focus on maximising workers’ health and safety and providing a safe working environment by controlling dust and fumes.
Emergency Stop System
Emergency stop buttons on the unit enable anyone to halt the machine immediately.
Explosion Vents
- Configuration option: To mitigate the risks associated with combustible products, explosion vents can be added to the filter house.
Operation and Maintenance Lights
- Configuration option: Operational and maintenance lights can be fitted in key locations on the unit to give operators and maintenance workers visibility of components and illuminate working spaces.
Dust Collector Sizing. Factors.
Custom Designs. Meeting Your Site Needs.
Our fixed dust collectors are all designed by our in-house engineering team to meet specific applications and site conditions. A combination of airflow, air velocity, pressure, resistance and air-to-cloth ratios determines the appropriate size and ducting configuration. Incorrect sizing can result in high emissions, lowered productivity, reduced filter life and a hazardous or unsafe working environment.
Airflow. How much air the system needs to move.
The larger the space where extraction is required, or the greater the number of dust collection pick up points, the greater the airflow required.
Variable Speed Drives (VSD) or Variable Frequency Drives (VFD) can be used to adjust the airflow when there are fluctuating site conditions. This can help to reduce power consumption.
Air Velocity. The speed the air needs to move.
For dust to travel suspended in air it must travel at or above the minimum conveying velocity for that product. There are also risks such as explosion, toxicity and abrasion associated with certain dust types to be taken into account.
Low air velocity can cause dust build up within ducting and lead to poor dust capture and fires. This can also create an increased explosion hazard. High air velocity can cause premature wear in the duct work by means of abrasion or can break up delicate conveyed products such as food and pharmaceuticals.
Air-to-Cloth Ratio. Volumetric flow rate of air through a dust collector’s intake divided by the total cloth area (m²) in the filters.
For dust collectors to capture dust from the air-stream, they must have a sufficient number of filters. Maintaining an adequate air-to-cloth ratio enables the dust collector to operate at peak efficiency.
Dust types and the amount of dust per cubic meter are all determining factors.
Pressure and Resistance. Pressure and resistance across the dust collection system.
The fan used in the dust collector must supply enough suction to overcome duct and fixed pressure losses from the collection point(s), through the dust collector and filters before exhausting clean air out of the system.
Resistance to airflow is created by the filters and ducting along with the dust being transported.
