Common problems and answers of neutek compressed air drying filter

1 What is the basic working principle of neutek drying filter (nt-105f nt-107f nt-110f nt-111f nt-120f nt-140f nt-180f)? There are three ways for the dryer to remove 100% of the water droplets in the compressed air: condensation, small whirlpool and evaporation Water droplets larger than 1 μ m gather in the coalescing filter and flow out through the drain valve which is often open When passing through the second filter, the water drops smaller than 1 micron rotate in hundreds of small whirlpools, which gather in the center of the whirlpool and decompose into water vapor (small whirlpool phenomenon) The water vapor and oil droplets that are not transformed into water droplets by the small vortex phenomenon are absorbed by the filter element of the second stage filter, the compressed air is lower than 100% relative humidity, and the trace oil still exists, and the water is evaporated into the compressed air The special design of three-stage filter device combined with the direction of compressed air ensures the effect of neutek filter 2 What are the three filter elements used for? * filter elements separate 95% of water, oil and impurities from the air The second stage is to collect and drain water in time through a large water reservoir with a honeycomb lower shell The third stage contains a special material filter element which can evaporate any residual water 3 What is the purpose of honeycomb water storage? The honeycomb water storage device collects and discharges the water droplets condensed by the filter element, and the honeycomb network structure can prevent the air flow with the condensed water from passing through the device 4 How to prevent water from gushing out of the drain valve? Connect the flexible plastic pipe to the connector at the bottom of the drain valve 5 Can the sound of escaping compressed air and water be quiet? A silencer can be installed between the drain hose and the manual drain valve or a neutek automatic drain can be used instead 6 What is an automatic drain valve? The automatic drain valve is a device that the filtered water flows to the drain valve, the rising water level float ball drives the ejector pin to open instantly, and the water and impurities drain with the compressed air instantaneously 7 How long does the automatic drain valve keep open? Just allow enough time for the collected water and oil to drain, usually less than half a second 8 Does neutek drying filter (nt-105f nt-107f nt-110f nt-111f nt-120f nt-140f nt-180f) need special pressure regulating valve? Any pressure regulating valve can be installed on the NEUTEK dry filter 10 How do we judge when the filter element needs to be replaced? * the signal is an increase in pressure loss, which will not occur if the filter is replaced regularly The pressure difference display can indicate whether the filter element is "good" or "needs to be replaced" 11 What are the spare parts in neutek drying filter (nt-105f nt-107f nt-110f nt-111f nt-120f nt-140f nt-180f)? We have mounting bracket, fixing bolt and plastic drain hose 12 Will neutek dry filter (nt-105f nt-107f nt-110f nt-111f nt-120f nt-140f nt-180f) freeze in winter? No Neutek filter is designed to continuously discharge water as long as there is pressure in the system When the pressure stops, there is no air or water in the system to be frozen, and no new water will form 13 Can the filter element be cleaned and reused? * the filter element can be cleaned The second filter element cannot be cleaned If the second filter element is cleaned and reused, the cotton fabric in the cotton filter element may be blown into the air flow, so it is not recommended to reuse 14 When does the filter element need to be replaced? * if the filter element is cleaned every year, it can last for several years The second filter element can be replaced regularly according to the actual situation or when the pressure drops by 0.7kg/cm (10psi) Does neutek filter (nt-105f nt-107f nt-110f nt-111f nt-120f nt-140f nt-180f) have differential pressure display? Yes 16 We can't see whether the second filter element needs to be replaced Can the filter element tube be designed transparent? No Because no transparent material can stand the Zui pressure that neutek should bear, the aluminum tube is used to install the filter element 17 Is it difficult to change the filter element? It's easy When replacing the filter element, it is not necessary to remove the filter from the pipe As long as the upper screw is loosened, the pipe with filter screen can be taken out, and then the new filter element can be inserted and then the screw is tightened 18 Why is it necessary to gradually release the pressure when replacing the filter element? If there is still pressure in the pneumatic system, the one-step design is dangerous, so it is necessary to loosen the screw carefully to release the pressure step by step 19 What are the consequences if the filter element is not replaced? The pressure in the pneumatic equipment will gradually reduce until the pneumatic equipment tools can not work normally, and the neutek drying filter can no longer effectively remove water, oil and impurities 20 Why use aluminum tube? Because the aluminum tube is light and can withstand the pressure requirements of filter users 21 Will aluminum pipe be corroded by acid in air system? Under normal pneumatic system, it is generally not We have not encountered such problems since neutek filter production and sales 22 What are these filter elements made of? * the filter element is made of environmental friendly plastic, and the second filter element is made of cotton mesh woven with stainless steel wire 23 Use neutek drying filter (nt-105f nt-107f nt-110f nt-111f nt-120f nt-140f nt-180f), and do you need to drain water for the compressor? The compressor still needs to be drained This makes the air cleaner and extends the filter life The neutek automatic drain valve can be installed on the compressor without manual drainage 24 Can neutek dry filter (nt-105f nt-107f nt-110f nt-111f nt-120f nt-140f nt-180f) remove water? 99.99% of the water droplets can be removed and the remaining water droplets can be evaporated And water vapor will not damage the equipment, stain the paint surface, nor damage the pneumatic operation process Only water in the form of a liquid can cause these problems Neutek dry filter can remove almost all water drops and convert the remaining harmful water drops into harmless water vapor 25 We can hardly believe that the neutek filter can remove 99.99% of the water? Under the condition of 40 ℃, room temperature 32 ℃, 80% relative humidity test, different types of neutek drying filters can remove the following water per hour: 105F 170g / h (6oz / h), 110F 170g / h (6oz / h), 120F 170g / h (6oz / h) 140f 170g / h (6oz / h) 180f 170g / h (6oz / h) 26 Does neutek dry filter (nt-105f nt-107f nt-110f nt-111f nt-120f nt-140f nt-180f) remove water every minute? Yes The system is under pressure every second, so the neutek drying filter is also working every second The water captured every second is collected by the honeycomb water reservoir, and then discharged by the automatic drain valve or T-valve (swing drain) 27 How much oil can be removed from the air? About 99% of the bad oil and its decomposed matter in the air can be eliminated by neutek drying filter 28 What is the function of T-valve and t-pin? T-pin prevents T-valve from closing completely, and there is continuous air discharge to make the ultra dry filter dynamic all the time Only a small amount of air leaks through the valve About 0.1-0.3 cubic meters of air is lost from T-valve every hour Open T-valve and move t-pin up and down to remove any small particles that may block T-valve 29 How much air is lost by swinging the drain valve? Swing the drain valve every day to consume 0.8-2.7 cubic meters of air, which costs USD $0.14 per cubic meter of air Zui, and USD 0.11-0.38 per neutek drying filter every day 30 How much pressure drop is caused by neutek drying filter (nt-105f nt-107f nt-110f nt-111f nt-120f nt-140f nt-180f)? When the pressure of the compressed air pipeline is 7kg / cm2, the pressure through the neutek drying filter decreases by 0.14kg/cm2, and the pressure of other ordinary filters decreases by 0.3-0.5kg/cm2 31 What is the Zui high working pressure?
