SAFELY CAPTURE AIRBORN OILS AND COOLANTS

The metalworking fluids (MWF) commonly used during machining processes—oils and coolants—generate mists in the work environment. These airborne contaminants must be carefully controlled to prevent worker accidents and health problems and to ensure compliance with OSHA, NIOSH and ACGIH regulations.

Oily floors are a slipping hazard. Toxic vapors are a health hazard. Left unchecked, machining mist will be inhaled by machine operators, build up on shop floors and surfaces, and ruin equipment, electronics, and machined parts. Oils and coolants also create a dirty and unpleasant work environment if they are not filtered from the air before they settle.

Mist collectors mitigate all of these hazards by safely removing oils and coolant at their source or from the air before they are inhaled or settle in the workplace. Your workers’ health and safety depend on the effective collection of all coolant mist aerosols, vapors, and fumes generated in your machining center.

Choosing the right mist collector for your shop can seem daunting. At Camfil APC, we strive to remove that complexity to solve your mist collection problems. Our friendly team of experts is always ready to chat and answer your questions and concerns.

Health Hazards of Metalworking Fluid Mists
  • Respiratory disorders - The respiratory tract and mucous membranes become inflamed, leading to asthma, chronic bronchitis, and hypersensitivity pneumonitis.
  • Skin problems – Prolonged exposure can cause contact dermatitis and skin irritation.
  • Cancer – Exposure to carcinogens can cause pancreatic, colon, bladder, and liver cancer and tumors in the brain, respiratory organs, and digestive tract.
  • Allergies– Prolonged contact can cause allergic contact eczema or bronchial asthma.
  • Nerve damage – Exposure to toxins can cause impact organs and nerves.
Regulations for Metalworking Fluid Emissions
  • OSHA - The Occupational Safety & Health Administration uses two air contaminant permissible exposure limits (PELs) for MWFs:
    • 5 mg/m3 for an 8-hour time-weighted average (TWA) for mineral oil mist
    • 15 mg/m3 for an 8-hour TWA for Particulates Not Otherwise Classified
  • NIOSH - The National Institute for Occupational Safety and Health has set a much stricter recommended exposure limit (REL) for MWF aerosols. They must be limited to 0.4 mg/m3 for a 10-hour TWA for a 40-hour work week concentration for thoracic particulate mass (the fraction of inhaled particles capable of passing beyond the larynx during inhalation).
  • ACGIH – The American Conference of Governmental Industrial Hygienists has set two threshold limit values for mineral oils:
    • 5 mg/m3 for an 8-hour TWA
    • 10 mg/m3 for a 15-minute short-term exposure limit

  • Innovative filter media – Our standard filter material self-cleans by optimizing drainage of the separated coolant.
  • Easy filter changeout – Mist collectors operate practically maintenance-free, and filter changes don’t require tools.
  • Unparalleled cost-effectiveness – All collectors operate safely and are durable enough to provide long maintenance intervals.

HANDTE EM PROFI MIST COLLECTOR

The Handte EM Profi emulsion/coolant mist collector offers the highest available collection efficiencies plus the ability to run 24/7 for reduced maintenance, service ease, and lower operating costs. The unit can handle the heaviest loads encountered in the industry to clean up contaminants generated during milling, drilling, tapping, turning, grinding and other machining processes that utilize emulsion mist coolants.

Features
  • Self-cleaning
  • Automatic sprayer system reduces filter buildup
  • Corrosion-proof and washable two-stage filtration system
  • No leaks – guaranteed!
  • Easy maintenance

 

Multi-stage Filtration

We consistently achieve high separation performance by designing our filter materials to meet specific needs or to handle a given droplet spectrum. We do this through optimized, flow-engineered, multi-stage design:

  • SELF-REGENERATING SEPARATION STAGES – Self-regeneration is achieved by using high efficiency, stainless steel woven mesh filters located at a slight angle within the units. This combination provides optimum separation efficiency and drainage.
  • FINAL FILTER – Final safety HEPA filters are 99.97% efficient on .3 micron and larger particles.
  • SIMPLE SETUP – Handte EM Profi units are modular for capacity/sizing and customizable with many optional accessories.

User-Friendly

The Handte EM Profi is extremely easy to maintain. Large service doors and quick-lock latches make it possible for a single technician to easily perform installation and removal from the floor, eliminating extra manpower and lift equipment. Service life between changeouts is up to six years for mist separation filters and two years for HEPA filters. Large maintenance doors and quick-clamping elements facilitate fast, toolless filter replacement. Due to these features, Handte EM Profi collectors offer substantial savings through reduced downtime, longer changeout cycle intervals, and increased productivity and reliability.

Modular Design

  • Minimum space requirement, maximum performance
  • System can be expanded in the future as needed
  • Short delivery time
  • Easy transport and installation

Basic Modules

  • Ground/platform versions with optional return pump station (for recirculating separated fluids)
  • Filter module (contains main and final filter)
  • Connection box for use with an external fan. The connection can be on left, right or rear side.
  • Built-in fan in compact design enclosure with integrated sound insulation
  • Top-mount fan

Models/Air Volume

  • 3.0/1,700 CFM

Innovative System Design

Cascade collector design with ascending filter classes allows filter combination matching for the specific machining process.

FAN
Integrated or top-mount fans provide reliable, constant extraction power to meet the application requirements. With integrated fans, acoustic insulation is included in the housing. The units are delivered ready for plug-and-play without any additional assembly required at the installation.

FLUID RETURN
Due to the self-regeneration design of the filter elements, the separated cooling lubricant is released from the filter media and drains to the fluid return sump at the base of the unit. Through either a recirculation pump or siphon, the collected coolant can be returned for treatment, reuse or disposal.

FILTER CASSETTE WITH MEDIA SEPARATORS FOR MAXIMUM FILTER AREA - The CoaPack filter element provides maximum filter area within a compact design. This construction ensures a uniform flow, optimum use of diffusion and coalescence, which is a relevant separation mechanism for ultra-fine mists. The small load acting on the filter surface reduces the energy consumption and significantly increases the service life of the filter element.

IDEAL DRAINAGE PERFORMANCE FOR OPTIMUM FILTER REGENERATION
The premium filtration effectiveness of the Handte Oil Expert is due to the ideal balance between separation performance and regeneration of the separated cooling lubricant from the filter media. This is achieved by using drainage-friendly materials together with special drainage support mats, protective screens, and spacers.

CLEAN MAINTENANCE, EASY FILTER CHANGE
Thanks to its functional design, the Handte Oil Expert is practically maintenance-free. Quick-acting clamps ensure that changes of the filter cartridges are easy and require no tools, ensuring minimum downtime. Filter cartridges are accessed via the service door(s) and a transport trolley is available, providing drip-free removal of the filter cartridges—a perfect complement to our service concept.

Fast-acting clamps ensure easy filter changeout, and the available transport carriage provides drip-free removal of the filter cartridges.
