Your Reliable Filter Carts Manufacturer in China
As a professional filter cart manufacturer, LianDa boasts over 20 years of production experience, offering a full range of six types, including vacuum dehydrators, high-viscosity filter cars, and coalesce skids. With a filtration precision as fine as 1 micron, it can handle liquids with viscosities up to 10,000 SSU and holds ISO 9001 certification. Whether it’s hydraulic oil, lubricating oil, gear oil, or transformer oil, LianDa provides complete oil purification solutions from particulate filtration to deep dehydration, extending equipment life and reducing maintenance costs.
LianDa Filter Carts: Full Range – Six Configurations to Cover Every Application
Dual dehydration via vacuum and heating, simultaneously removing particles, free water, emulsion water, and dissolved water.
Lightweight and handheld, operated by one person, suitable for confined spaces and remote sites.
Circulating heating + high-pressure pump, designed for oils with viscosities up to 10,000 SSU.
Wheel-mounted and portable, with quick-connect fittings; one filter cart can serve multiple machines in rotation.
Coalesce filter element coalesces water droplets, efficiently separating emulsion water and free water from oil.
Two-stage, dual-element design, designed for heavily contaminated oils and high-abrasive debris conditions.
Yes, this is precisely the main advantage of LianDa renal loop filters. The LianDa filter cart is connected to your oil tank via a parallel offline loop. While the machine is running normally, the filter cart simultaneously circulates and purifies the oil. No downtime is required. Generally, it pumps approximately 10% of the tank capacity per minute, and the filter cart continues to run until the target cleanliness level is achieved.
Key variables are liquid viscosity, contamination type (particulate, moisture, or both), tank capacity, and target ISO cleanliness code. For standard hydraulic fluids and lubricants below ISO VG 680, handheld filtration carts cover most applications. For viscosities exceeding ISO VG 680 or 500 SSU, a LianDa high-viscosity filter cart is required. For moisture contamination, choose a vacuum dehydrator or a combined skid. For heavily contaminated liquids, choose a high-solids-content filtration cart. Tell LianDa your specifications, and we will determine the appropriate model.
Yes, and most maintenance teams skip this step. New drummed oil contains an average of 7 grams of particulate contaminants per 100 gallons, exceeding the cleanliness requirements of most hydraulic and lubrication systems.
Coalescing skids remove free and emulsified water by separating larger droplets, making them suitable for fuel and hydraulic systems. Vacuum dehydrators additionally remove dissolved water through vacuum and heating, making them ideal for transformer oil and turbine lubrication systems.
A common guideline is circulating about 10% of the tank capacity per minute. Actual flow rate and operating time depend on contamination level, fluid condition, and the required cleanliness standard or ISO code target.
Yes. LianDa offers pneumatic motor drive options and explosion-proof motor configurations for hazardous environments where the use of ordinary motors is not permitted. Tell us your explosion-proof zone rating, and we will specify the appropriate drive configuration.
