LFHY-2000 Mobile Cartridge Dust Collector

In modern industrial environments, dust generation points are rarely fixed. Welding stations, grinding benches, 

material transfer points, batch mixing areas, and maintenance zones all require on-the-spot dust control—yet permanent

 ducted systems are costly, inflexible, and often impractical. The LFHY-2000 Mobile Cartridge Dust Collector is engineered 

to solve this exact challenge: a self-contained, wheeled filtration unit that brings high-efficiency dust collection directly to 

the source, wherever it may be.

This new-generation model integrates an optimized box housing, a high-efficiency centrifugal fan, a premium pleated

 cartridge filter, a convenient dust collection tray, and an intelligent microcomputer control system into a single compact

 assembly. Its operation is both simple and scientifically robust: dust-laden air is drawn through a flexible suction hood (or arm) 

by the fan, entering the filtration chamber. As the air passes through the cartridge media, particles are captured on the outer

 surface through a synergistic mechanism involving gravitational settling, inertial impaction, direct interception, Brownian

 diffusion, and electrostatic attraction (for synthetic media). The purified, clean air is then discharged through the outlet, 

and can be safely recirculated directly into the workshop—saving energy and reducing HVAC load.

The entire filtration process is the result of multiple physical forces working in concert, ensuring that even sub-micron particles

 are effectively removed. Our latest LFHY-2000 incorporates several significant upgrades over previous models: a more 

energy-efficient motor, a quieter fan assembly, a higher-capacity filter cartridge with nano-coated media, and a smarter 

control panel that offers both automatic and manual cleaning modes.

Key Product Features – What Sets the New LFHY-2000 Apart

1. Ultimate Mobility – Go Anywhere, Clean Anywhere: Equipped with four heavy-duty swivel casters (two lockable), 

the LFHY-2000 can be effortlessly maneuvered to any point within your workshop, production floor, or outdoor staging area.

 It is never constrained by fixed ductwork or permanent piping. Whether you need to capture weld fume at a temporary

 workstation, vacuum spilled powder at a bagging station, or extract dust from a moving conveyor transfer point, this unit

 follows the work.

2. Precision Positioning & Stability: The universal casters feature robust braking mechanisms, ensuring the unit stays firmly 

in place during operation—even when the suction arm is extended or moved. This prevents accidental rolling and protects 

operators from hose strain.

3. Unparalleled Filtration Efficiency: At its rated airflow capacity, the LFHY-2000 achieves a dust removal rate of ≥99.9% 

(for particles ≥0.5 microns). The treated exhaust air is exceptionally clean—well below occupational exposure limits—and

 can be directly recirculated into the workshop environment without the need for external venting. This not only improves 

indoor air quality but also significantly reduces heating and cooling energy losses.

4. Premium PTFE-Coated Filter Cartridge (Imported): The heart of the system is a high-precision, imported filter cartridge 

featuring a micro-porous PTFE (polytetrafluoroethylene) coating on a durable polyester substrate. This advanced media 

offers exceptional release properties—dust particles do not adhere firmly to the surface, making cleaning easier and more 

effective. As a result, the filter maintains a consistently low pressure drop over extended periods, consumable costs are

 remarkably low, and the cartridge requires infrequent replacement—typically every 12–24 months under normal use. 

This translates to significant savings in both parts and labor.

5. Constant Airflow & Stable Purification Capacity: The LFHY-2000 is designed to maintain a steady intake airflow regardless

 of filter loading, thanks to its robust fan curve and automatic cleaning logic. The system ensures that purification capacity 

does not degrade between cleaning cycles. Users can select between automatic pulse-jet cleaning (triggered by differential 

pressure or time) or manual cleaning (via a push-button), depending on operational preferences and dust characteristics.

6. Intelligent, Safe Control System: The microcomputer controller features a user-friendly interface with real-time status indication. Key safety features include: (a) high-voltage leakage protection for operator safety, (b) motor overload protection, (c) filter clogging alarm (optional), and (d) an emergency stop button. The control logic is stable, reliable, and tested to withstand industrial electrical noise.

Working Principle – Step-by-Step Filtration Process

1. Intake & Dust Capture: The operator positions the flexible suction arm (equipped with a flared hood or nozzle) directly over

 the dust source. The fan creates a negative pressure, drawing dust-laden air into the arm and through the inlet duct.

2. Pre-Separation: Upon entering the box housing, the air stream undergoes a 90° directional change. Coarse and heavy particles

 lose momentum due to inertia and gravity, dropping into the lower dust collection tray—this reduces the burden on the cartridge.

3. Cartridge Filtration: The remaining fine dust-laden air passes through the pleated PTFE-coated cartridge from outside to inside. 

Dust particles are captured on the media surface through a combination of inertial collision, direct interception, Brownian

 diffusion (for sub-micron particles), and electrostatic effects. The cleaned air exits the cartridge interior.

4. Clean Air Discharge: The purified air flows through the fan and is discharged from the outlet grille. Because the exhaust is

 cleaner than ambient workshop air, it can be safely recirculated—reducing the need for make-up air conditioning.

5. Cleaning Cycle: Over time, the pressure drop across the cartridge increases. The microcomputer controller either 

automatically initiates (or the operator manually triggers) a compressed-air pulse that reverses the airflow through the cartridge.

 This shockwave dislodges the accumulated dust cake, which then falls into the collection tray.

FAQ – Frequently Asked Questions (Newly Added)

Q1: How long does the filter cartridge last before replacement?

A: With the new PTFE-coated media and under typical industrial dust loads (e.g., welding fume or wood dust), the cartridge lasts

 18–24 months. For highly abrasive or sticky dusts (e.g., paint powders or wet grinding sludge), life may be 6–12 months. 

We recommend monitoring the pressure drop: if cleaning no longer reduces it below 800 Pa, replacement is due.

Q2: Can I use the LFHY-2000 for wet or oily dusts?

A: The unit is designed for dry dust collection only. For oily or wet particles (e.g., mist from machining fluids), we offer a 

separate oil-mist cartridge or coalescing pre-filter option. Please consult our engineering team for such applications to avoid

 filter blinding.

Q3: How do I clean the filter cartridge—automatically or manually?

A: Both modes are available. In automatic mode, the microcomputer triggers a pulse-jet cleaning cycle based on a preset time 

interval or differential pressure setpoint. In manual mode, the operator simply presses a button on the control panel whenever 

they observe a pressure increase. Manual cleaning is useful for intermittent operations or when compressed air supply is limited.

Q4: What is the noise level in actual operation?

A: Our updated model measures ≤78 dB(A) at 1 meter—significantly quieter than the previous 80 dB specification. 

This is achieved through improved fan balancing, acoustic foam lining inside the housing, and vibration-damping feet. 

For further noise reduction, an optional silencer can be fitted to the exhaust.

Q5: Can the suction arm be extended or replaced with a different hood?

A: Yes. The standard arm is 2,000 mm long with a 160 mm diameter. We offer extensions up to 4,000 mm and a range of hood 

attachments: flared round hood, rectangular slot hood, crevice nozzle, and brush-tip nozzle for delicate surfaces. All are

 quick-connect compatible.

Q6: Is the LFHY-2000 safe for combustible/explosive dusts (e.g., aluminum, grain, coal)?

A: For combustible dust applications, we offer an ATEX-compliant variant with anti-static cartridge media, spark-arresting inlet 

baffles, grounded casters, and a non-sparking fan impeller. Please specify your dust type and hazard zone when ordering so

 we can supply the correct safety configuration.

Q7: How much compressed air does the pulse-jet cleaning consume?

A: Each cleaning pulse uses approximately 5–8 litres of compressed air at 0.5 MPa. With typical cleaning intervals of 15–30 

minutes (automatic mode), total consumption is negligible—typically under 0.2 m³/min on average. If compressed air is 

unavailable, the manual cleaning option can be operated with an external portable air bottle.

Q8: Can the unit run continuously for 8-hour shifts?

A: Absolutely. The motor is rated for continuous duty (S1 service) with thermal overload protection. We recommend emptying

 the dust collection tray at the end of each shift to prevent overflow and maintain suction performance.

Q9: What is the warranty and after-sales support?

A: We provide a 24-month warranty on the housing and motor, and a 12-month warranty on the filter cartridge (against defects). 

Spare parts (cartridges, seals, control boards, casters) are available from our local stock. We also offer on-site maintenance 

contracts and remote diagnostic support.

Q10: Is the unit easy to assemble upon delivery?

A: Yes. The LFHY-2000 arrives mostly pre-assembled. You only need to attach the suction arm (two bolts), plug in the power cord, 

and connect the compressed air line (if using automatic cleaning). Full illustrated instructions and a quick-start guide are included. 

Most customers have the unit running within 15 minutes of unpacking.

Q11: Can I use two suction arms simultaneously with one unit?

A: Yes. Our dual-arm configuration allows two operators to work independently from the same unit. However, total airflow is

 shared between the arms—if both are fully open, each receives approximately 1,000 m³/h, which is still effective for many

 applications. For maximum suction on a single point, we recommend the single-arm configuration.
