Oil Mist Coalescers

Oil mist and smoke, oftenseen in the exhaust of vacuum pumps, can be harmful to both equipment andworkers. These pollutants waste valuable oil and pose health risks in theworkplace. Graver Technologies offers oil mist coalescersor oil mist filters such as PMEseries or FE style filters that remove harmful oil mist and smoke, improvingworkplace safety, productivity, and pump efficiency. These filters can beinstalled downstream of the vacuum pump before discharging into the atmosphere.The cylindrical and multi-stage element removes the heavy concentrations of oilmist and oil smoke from the exhaust stream of oil-sealed, oil-lubricated, andmechanical vacuum pumps.

How Our Oil Mist Coalescers Work?

Graver’s industrial oil mist coalescers operate through a multi-stage process designed to capture and remove airborne oil particles efficiently. Here’s the detailed explanation of how our oil mist filters:

Air intake: In the first step, the contaminated air containing fine oil mist enters the filtration unit from machinery such as compressors, turbines, or vacuum pumps.
Pre-filtration stage: The larger oil droplets and particles are then removed through an initial filter layer to reduce the load on the main filter.
Oil Coalescing Filter: The core filtration media captures microscopic oil droplets and forces them to collide and combine (coalesce) into larger droplets.
Separation & drainage: Coalesced oil droplets become heavy and are separated from the airflow. These droplets drain down for collection or disposal.
Clean air discharge: The purified air, now free from oil mist, is safely released back into the environment or ducting system.
System efficiency: The process functions continuously with minimal maintenance, making it ideal for demanding industrial applications.

Adaptable filter elements: It is equipped with filter cartridges in various materials and temperature ratings to ensure optimal performance across different applications.

‍Why Choose Graver’s Oil Mist Filters?

Our oil mist collector filter captures fine oil aerosols from the air and coalesces tiny droplets into larger ones using advanced oil coalescing filter technology. The result is only clean air returning to your facility, with several business benefits:

Cleaner operations: Our filtration system keeps your facility’s air clean and work areas free of oily residues. This means no more slick surfaces or haze, improving overall cleanliness and safety in your operations.
Equipment protection: The system prevents oil deposits from collecting on machinery, protecting critical equipment from wear and corrosion. Your vacuum pumps last longer and perform at their best, reducing the risk of unexpected downtime.
Regulatory compliance: Capturing oil mist at the source helps you meet environmental and workplace regulations. You stay compliant with clean air standards and avoid potential fines or liability issues.
Reduced maintenance costs: Less oil mess means your team spends less time and money on cleanup and repairs. Equipment runs longer between service intervals, cutting down on maintenance downtime and saving on replacement parts.
Reliable performance: Engineered by Graver Technologies for heavy-duty industrial use, our oil mist filters deliver consistent, high-efficiency performance. The durable design ensures long service life and dependable operation, so you can count on continuous protection with minimal interruption.

Data Sheet

Frequenty Ask Questions

What are Heavy Metals?

Heavy metals are naturally occurring elements with high atomic weights and densities, typically greater than 5 g/cm³. They include lead, mercury, arsenic, and cadmium. They can be toxic even in trace amounts, accumulating in organisms and causing health risks.

What are the Problems with Heavy Metals in Water?

Heavy metals in water can cause severe health effects such as neurological damage, kidney failure, and cancer, even at low concentrations. They persist in ecosystems, bioaccumulate in the food chain, and disrupt aquatic life.

What are the Heavy Metal Parameters for Water?

Heavy metal parameters include concentration levels, toxicity thresholds, bioavailability, and the presence of specific metals like Pb, Cd, Hg, and Cr. These are regulated by agencies like the EPA and WHO to ensure water safety.

How do you Calculate Heavy Metal Concentration in Water?

Heavy metal concentration in water is measured using techniques like atomic absorption spectrometry (AAS), inductively coupled plasma mass spectrometry (ICP-MS), or colorimetric analysis. The results are expressed in micrograms per liter (µg/L) or milligrams per liter (mg/L).

What is the Permissible Limit of Heavy Metals in Water?

The permissible limits vary by a regulatory body, but for drinking water, the WHO and EPA set limits such as Lead (Pb) ≤ 0.01 mg/L, Mercury (Hg) ≤ 0.001 mg/L, and Cadmium (Cd) ≤ 0.003 mg/L.

What is the Mechanism of Heavy Metal Adsorption?

Heavy metal adsorption involves ion exchange, surface complexation, and precipitation on adsorbent materials like activated carbon, biochar, or nanomaterials, reducing metal ions from contaminated water. Adsorption efficiency depends on pH, temperature, and adsorbent type.

How is Graver’s oil mist filter different from others?

Graver Technologies offers high-efficiency oilcoalescing filters built for industrial demands, with low pressure drop,durable construction, and customizable designs to match your system.

Can I retrofit your oil mist filters into my existing setup?

Yes.Our industrial oil mist filters are available in various sizes, materials, andconnection types, making integration into existing systems seamless.

Are your filters compliant with industry standards?

Yes, our products are engineered to meet or exceedindustry performance and safety standards, including those for emissions andworkplace air quality.

What applications require oil mist filtration?

Oilmist filtration is essential in systems with vacuum pumps, compressors,gearboxes, and turbines—especially in manufacturing, automotive, and powergeneration facilities.

How often do the filters need to be replaced?

Filterreplacement depends on your operating conditions, but our systems are designedfor extended life and easy maintenance. We offer support to help you set theright maintenance schedule.
