Apurio - MQL Separators
MQL separators are specialized mechanical filtering systems employed in industrial settings where machining with minimum quantity lubrication (MQL) results in air contaminated with dust and coolant lubricant. These systems initiate the filtration process through a pre-filter to capture dust, while a downstream coalescence filter efficiently separates the lubricant. As droplets merge and form larger ones within the filter, gravity aids in their removal, contributing to a self-cleaning mechanism for filter elements. Additionally, when air re-circulation within the facility is required, an optional HEPA filter stage can be integrated for fine particulate filtration. Apurio offers these separators as scalable solutions, from standalone units to large central systems, accommodating diverse industrial needs and ensuring safe, cost-effective exhaust air purification.
MQL separators are mechanically filtering separators used for air contaminated with dust from machining with minimum quantity lubrication (MQL). In this process, the dust is separated by a pre-filter, while the coolant lubricant is separated by a downstream coalescence filter (coalescence: merging). In this process, the droplets in the exhaust air combine in the filter medium to form larger droplets, flow downwards due to gravity, and drip off. This results in a continuous self-cleaning of the filter elements. If the air is not to be vented outside but returned to the building, a HEPA (High Efficiency Particulate Air filter) stage (particulate filter) can be added downstream.
