Polytech Filtration Systems products

Polytech offers conventional vacuum filters designed to ensure consistent, reliable filtration of water-based machine tool coolants in industrial settings. These filters operate by utilizing the pressure differential between atmospheric pressure in the contaminated coolant tank and the reduced pressure created by the centrifugal pump`s suction, enabling the coolant to pass through a non-woven filter fabric for effective filtration. The system is equipped with a robust sludge conveyor that efficiently handles spent filter media and solid contaminants, guaranteeing uninterrupted coolant flow to machine tools through a clean coolant reservoir. Unlike pressure filters, Polytech`s vacuum filters operate automatically and require less labor-intensive maintenance, thereby reducing downtime. Designed for industrial applications, these filters are recognized for their durability and adaptability across various installation setups.

Polytech's patented low entry vacuum filters are innovatively designed to tackle challenges often encountered when working with heavily aerated fluids. These filters function effectively even when the coolant entry height is minimized, such as 10 inches, and can manage aerated grinding and cutting oils without the need for additional transfer pumps or tanks. This optimized design facilitates direct draining of the coolant from the machine tool into the filter section, eradicating issues posed by fibrous contaminants. The unique design allows for swift filtration and transfer of dirty coolant to an upper clean tank where entrained air is efficiently managed before the fluid is returned to the machine tool by a dedicated pump. Capable of self-adjusting to varying operating conditions, these systems offer a differential pressure at least 30% greater than conventional filters, enhancing media life and performance. The SL Series conserves space with its compact design, while the SLE Series allows for larger discharges, accommodating substantial swarf hoppers, providing adaptable solutions for various industrial applications.

Polyclon Whirlstream Hydrocyclones are engineered for efficient liquid filtration, targeting applications that demand robust solutions for contaminant separation. The technology operates by introducing contaminated liquid at high velocity into the hydrocyclone, propelling it into a specialized whirl chamber. As the liquid descends in the conical separation chamber, its velocity increases, causing solid contaminants to be flung against the chamber walls and separated. These contaminants settle to the bottom while the purified liquid reverses direction, forming an inner vortex that exits through a clean liquid outlet. This design supports diverse industrial applications with its capability for precise filtration adjustments tailored to specific needs. Additionally, Polytech Filtration emphasizes environmentally conscious operations by integrating energy-efficient technologies like hydrocyclones, conveyor dragouts, and centrifuge systems into their filtration solutions.

Polytech`s magnetic separators are engineered to effectively remove both ferrous and non-ferrous solid contaminants from coolants and oils, optimizing industrial operations such as grinding, honing, and lapping. By reducing the reliance on filter cartridges, these separators enhance cost efficiency and maintenance intervals. The design features a magnetic drum composed of alternating permanent magnets and steel discs, extending the magnetic field through magnetized discs for enhanced performance without the use of high-cost magnets. In machining operations like broaching, milling, and drilling, these separators effectively decrease small fines buildup in coolant, thus prolonging machine tool lifespan. Additionally, a comb type scraper coupled with an adjustable discharge chute ensures efficient sludge removal. Customization is available to meet specific application requirements, with higher flow rates obtainable upon request.

Polytech`s gravity bed filters are an automatic filtration solution utilizing low-cost bulk roll filter media, ideal for environments with moderate levels of contaminants. These filters work by allowing the contaminated liquid to pass through a non-woven synthetic filter fabric supported by a conveyor belt. As contaminants build up on the media, the liquid flow reduces, raising the liquid level and triggering a float switch that activates the conveyor to advance the media. This design eliminates the need for seal maintenance present in deep bed filters that use submerged edge seals by containing the entire liquid pool in the filter paper. Gravity bed filters can be provided as a filter chassis alone or as a complete system with a tank, pump, and electrical controls, and they may be integrated with other filtration systems to meet specific clarity requirements.
