\"mist<\/a>

Primary Control Mist Collector mounted on CNC Machine with secondary control mist collector hanging from the ceiling.<\/p><\/div> Mist collectors filter the air in machine shops in order to remove harmful oil mist from CNC machines, milling and grinding processes. These systems are commonly used for CNC machine shops to eliminate oil mist. However, they can also be used to collect and filter systems with coolant mist, water mist or other oil mist.<\/p>\n

Oil mist is created when metal working fluids come in contact with milling or grinding processes and are dispersed into the air. Metalworking fluids are used to reduce friction, providing cooling and prolong the life of tools. Oil mist can become oil smoke when exposed to high temperatures and the oil starts to burn before emitting into the air. <\/p>\n

There are two primary types of mist collectors:<\/em><\/strong><\/h3>\n

Primary Control Mist Collectors<\/strong> \u2013 Primary control mist collectors are mounted on the machine and filter contaminates at the source. <\/p>\n

Secondary Control Mist Collectors<\/strong> \u2013 Secondary control mist collectors hang from the ceiling or can be stand mounted in order to catch additional mist from industrial processes. This type of mist collector is also feasible when direct mounting is not available. <\/p>\n

Why Install a Mist Collector?<\/h2>\n

Employers should install a mist collection system in order to improve employee health and safety, reduce worker lawsuits and liability, and meet government regulations restricting exposure to oil mist. Exposure to oil mist can result in eye and skin irritation, shortness of breath, vomiting, fever, rapid heartbeat, headaches, fatigue and burning sensation in mouth, throat or stomach. Oil mist exposure can also lead to an increased risk of cancer and diseases of the skin and respiratory system.<\/p>\n

OSHA (Occupational Safety and Health Administration), NIOSH (National Institute for Occupational Safety and Health) and ACGIH (Association Advancing Occupational and Environmental Health) all restrict the amount of oil mist employees are exposed to. The chart below details each organization\u2019s limit to oil mist exposure. If employers do not follow OSHA guidelines, OSHA can write citations which may result in fines. To determine the air quality in your location, industrial hygienists must be consulted.

How do mist collectors work?<\/h2>\n

Primary Control Mist Collectors<\/strong><\/h3>\n

\"Primary<\/a>\u2013 Step 1 \u2013<\/em><\/strong>
\nPre-filter – Mist enters mist pre-filter. Depending on the application, collected oil, coolant or water drains back into the machinery to be reused.<\/p>\n

\u2013 Step 2 \u2013<\/em><\/strong>
\nCarbon Pre-filter – Air is filtered through a carbon pre-filter where large particulates are captured.<\/p>\n

\u2013 Step 3 \u2013<\/em><\/strong>
\nMain Filter- Air is purified by passing through a final filter. This final stage will capture fine particulates. Filter choices include:
\n\u2022 ASHRAE Filter (up to 95% efficiency on particles down to 0.5 microns)
\n\u2022 HEPA Filter (up to 99.97% efficiency on particles down to 0.3 microns)
\n\u2022 ULPA Filter (up to 99.9995% efficiency on particles down to 0.12 microns)<\/p>\n

\u2013 Step 4 \u2013<\/em><\/strong>
\nFiltered Air – Filtered air is discharged back into work area.<\/p>\n

\n

Secondary Mist Collectors<\/strong><\/h3>\n

\"Secondary<\/a>\u2013 Step 1 \u2013<\/em><\/strong>
\n4 Cleanable Mesh Pre-filters – Mist enters the system and is filtered through a set of 4 cleanable mesh pre-filters.<\/p>\n

\u2013 Step 2 \u2013<\/em><\/strong>
\nOil Bag Filter – Any remaining oil and fi ne particulates are then filtered out of the air with the oil bag filter and drained into the drain plug to allow collection of oil for repurpose.<\/p>\n

\u2013 Step 3 \u2013<\/em><\/strong>
\nFiltered Air – Filtered Air is released back into the workspace through an adjustable four-way grate.<\/p>\n

Sentry Air Mist Collector Systems<\/h2>\n

Primary Control Mist Collectors<\/strong><\/h3>\n\"Primary<\/a>\n

The primary control mist collectors (Models 200, 300, 400, and 450) offer a compact and powerful solution to filter oil mist, water mist or coolant mist produced from industrial processes. This line of units mounts to the machinery to capture the oil from the source. Commonly these units are used for CNC mist elimination but can also be used for air filtration on other machines that produce oil, water or coolant mist. These unique and simple units provide ease of installation due to no external exhaust or ducting is required for air output. The source capture mist collectors features quiet operation, energy efficiency and minimal maintenance.
\nThe primary control mist collectors filter the air through a three filter system: cleanable mist pre-filter, carbon pre-filter and main filter with customizable options. The unique washable mist pre-filter collects mist and drains the oil back into the system for repurposing, depending on the application. The carbon pre-filter adsorbs chemicals eliminating fumes and smells. The main filter is available in ASHRAE, HEPA, or ULPA filter.<\/p>\n

Secondary Control Mist Collectors<\/strong><\/h3>\n

\"Secondary<\/a> The secondary control mist collectors (Model 2000) are designed to capture and collect excess mist commonly found in machining and tooling shops. Typical applications include general shop mist collection, open CNC lathes and waterjet machines that produce ambient mist, and other applications that produce oil mist, water mist or coolant mist. <\/p>\n

This system is commonly used in conjunction with the source capture mist collectors but can be utilized as the primary filtration unit as well. In particular, these units are ideal for situations where direct mounting is not available or feasible.
\nThe secondary control mist collectors use a five filter process that was designed to handle mist and other wet environments. This filtration process consists of four cleanable mesh pre-filters and one oil bag filter. Collected oil from the filters is drained into an oil drain plug to be repurposed. <\/p>\n

This unit can be installed by hanging from the ceiling, mounting to a fume extractor stand, placing on a cart or table, or mounting to a wall shelf. For large areas, multiple ambient air mist collectors are recommended to increase efficiency and create an optimal airflow pattern.<\/p>\n\"Secondary<\/a>\n
