Compare Nederman Mist & Smoke Collectors
Nederman oil mist and smoke collectors
99.95% efficient at capturing .3 µm
2-5 year filter life, low operating cost
No maintenance required
Only technology accepted by UAW
Easy installation, clamp-together ducting
Fluid drainage capacity guarantees maximum coolant retrieval and reduces coolant consumption
Centrigual Mist Collectors
Were only 50% efficient on sub-micron particles and required expensive after-filters to meet the required mist level.
Often these devices went out of balance, required frequent filter pad change-outs, motor replacements, and frequent final filter change-outs.
Media Mist Collectors (Cylindrical Cartridge Type, Bag/Envelope Filters, & Box Cell Filter Type)
Were only 70% efficient on sub-micron particles, required final filters to meet required mist levels, and frequent filter changes were required to maintain airflow through the system.
This group had the largest number of manufacturer’s providing systems with ASHRAE filters.
The solid waste and landfill space required with this technology ruled out this design.
The media units lost airflow during testing at intervals of 30-45 days out of 90-day cycles.
Nederman Oil Mist Eliminators are not equipped with FibreDrain™ technology and fall under this category when compared to our oil mist and smoke collectors.
Electrostatic Mist Collectors
Were 95% efficient on submicron particles, however, required excessive manual maintenance to keep level clean enough for the required permissible exposure limit or PEL.
The ESP continued to deliver airflow while dirty, however, on demanding or on high concentrations of mist/smoke the ESP required adding a second or triple pass to meet the mist levels.
With most manufacturers reducing maintenance staff and programs this was also ruled out.
Candle Bed Mist CollectorsCandle bed systems are similar to our coalescing fiber bed systems. However, in recent studies, the candle bed system exhibited the highest overall pressure drop demanding higher horsepower and energy requirements.
The candle bed system included oversized metal mesh pre-filter, centrifugal cartridge, candle bed deep filter, and a final DOP filter.
Candle bed filter systems may require a tandem unit for bypass operation for drain down on high production applications.
