Advanced High Performance Needle Discharge Method
Top
  The Needle Discharge Method used in the TN-4000 model has an ionized field spreading around a complete length of the discharging pole and is very much more efficient when compared to the conventional tungsten wire discharge method having the ionization occurring only around the wire. The TN-4000 with its highly efficient 392 needle discharge dust collecting system has an outstanding capability to trap the most minute airborne particles has already won the trust of many industries.
The inherent durability of the Needle Discharge System in TN-4000 unit solves the problem of broken wire which regularly occurs in units with a Wire Discharge System. In order to minimize the possible generation of ozone (ozone could be harmful for the human respiratory system and causes intensive metal oxidation) the operating voltage in TN-4000 unit is kept to a minimum 5000 Volts.   
 
High Performance Activated Carbon Fiber Filter 
Top
  The high performance Activated Carbon Fiber filter technology is adopted by the TN-4000 air purifiers to ensure the effective adsorption of all odors and most gaseous chemicals from the air in a cleaning area. The activated carbon fiber filter agglomerated with cellulose has an active surface area of 1000 -1600 m2/g. And this is about 200 times larger than surface area of conventional carbon fiber filter used by most other manufacturers. The microstructure of the activated carbon fiber filter is that most of the pores are on its surface not deep in the middle and inner space of activated granular carbon. This also results in about 50 - 100 times faster adsorption speed of the activated carbon fiber filter over  the conventional activated granular carbon one. 
  The utilization of Activated Carbon Fiber filter technology allows to achieve in TN - 4000 air purifieer unit the same wonderful adsorption capacity for odors and most gaseous chemicals in result of utilization a significantly lower amount of activated carbon. Beside that, activated carbon fibers generate very low amount of coal dust comparing to activated granular carbon. This also helps keep the interior environment clean.

Powerful Air Flow and Extremely Effective Air Circulation
Top
The TN - 4000 is a Powerful and Efficient Air Cleaning machine. It provides a very strong air flow, 1413 CFM (40 m3/min) and a ceiling installation ensures a dynamic air circulation based on the Coanda Effect. The air flow rate on the "High" setting (speed) is sized for optimum Coanda air distribution in large cleaning space. The Coanda Effect was named in honor of Henri M. Coanda, a pioneer French aeronautical engineer and scientist. The Coanda Effect is based on the principal of delivering clean air in a moving layer at a ceiling levels. The maximum clean air distribution through space is achieved since the moving air in the room trends to follow the ceiling surface until it reaches a wall or its velocity dissipates. In fact, the installation of the TN - 4000 unit in the ceiling in conjunction with a powerful air flow delivered from the side air outlets can make the air circulation in a room simply ideal.  
 
Ultra Thin Attractive Contemporary Design
Top
  Although there is a trend to install various air conditioning and other servicing equipment in the ceiling, as latest buildings become taller the room height is decreasing allowing lees and less room for its installation. The Ultra Thin Design of TN - 4000 air purifier allows to cope with this problem, as only 8 inch (20 cm) part of the overall height of 10.2 inches (26 cm) of the unit is recessing into the ceiling. This model proves the ability to purify efficiently the air even in limited spaces. A thin visible out coming part of the unit has an elegantly looking design which no doubts, meets a contemporary style and add to a decor of the recent buildings. Super Durable the all metal housing is built to last and provides no off gassing.
 
Easy Maintenance, Low Cost of Replacements Filters 
Top
TN - 4000 has a three stage air filtration system which requires minimum maintenance and has a minimal cost of replacement filters.
All parts of the air filtration system including the pre filter, washable dust collecting units (dust collectors), activated carbon fiber filter and deodorizing filter are easy to reach. Convenient, simplified and a time saving filters cleaning or replacement procedure makes these units easy maintenence, low operating cost air purification devices. 
 
 
Energy Efficient and Quiet Operation the Ceiling Built-in Air Purifier
Top
  The TN - 4000 despite a powerful air flow of over 1400 CFM provides a quiet operation (noise level under 50 dB) and draws only 114 Watts of power from electric power system. Beside that, because of the extremely efficient air circulation in the cleaning area, TN -4000 also minimizes the temperature difference between the upper and lower air layers. And this helps to save power by allowing air conditioner in the same room to run at a low speed.
Based on minimum three complete air changes per hour, one TN - 4000 can be effective for cleaning the air in areas up to 3500 sq. ft. (325 square meters). However, for best cleaning result, use one unit for each 2000 sq. ft. or 186 sq. m. cleaning area. The TN - 4000 air purifier provides a wonderful air cleaning result while occupying no office space at all.
