Oil-free VS Piston Compressor

   100% Oil-free Screw Air Compressor   Piston Air Compressor
Oil content The compressed air has an oil content of 0PPM and has passed the third-party international authoritative organization TUV class 0 oil-free certification in Germany When the oil scraper ring and packing box are worn out, lubricating oil will enter the cylinder in a gaseous or liquid form, causing the discharged compressed air to contain oil
Operational security When shutting down: the pressure is relieved by the vent valve, and there is no pressure in the compression chamber. When restarting, it can be started directly When restarting, it is necessary to use low-pressure air to open the air valve for unloading, which poses a risk of equipment failure due to improper operation
Vibration Good power balance, smooth operation, no need to fix the foundation during the operation of the unit, and the coin does not tilt Unbalanced force, large vibration, requiring fixed foundation or shock absorption device
Oil free safety 100% clean and oil-free compressed air, 100% avoiding the risk of oil pollution There is a risk of lubricating oil leaking into the compression chamber and spraying a large amount of oil after the failure of the oil scraper ring and the wear of the packing box create gaps
Water content Isothermal compression, the compression chamber temperature is generally only around 45 ºC, and the water vapor mixture is separated by a patented water vapor separation drum, resulting in low water content in the compressed air The working temperature of the compression chamber of the piston machine is around 180 ºC, and the exhaust temperature after passing through the aftercooler is around 85 ºC. The compressed air has a high water content
Fire safety The operating temperature is low, around 45 ºC, so there is no need to worry about equipment high-temperature self ignition or scalding accidents The temperature of the compression chamber can reach around 180 ºC, which poses a risk of high-temperature spontaneous combustion and personal burns.
Temperature The whole machine is cooled by water, and as long as the pressure and flow rate of the cooling water are ensured, the machine can operate stably at around 45 ºC for a long time The temperature inside the cylinder is around 180 ºC, which is prone to high temperature alarm and shutdown
Efficiency The direct connection between the host and motor has high transmission efficiency and low power loss, with a compression efficiency of over 95% The reciprocating plug type is generally a three-stage or 4 stage compression, with a complex structure and pipelines, high pressure loss, high specific power, and high power consumption
Particle impurities Water has a cleaning effect on the air. Impurities such as dust particles sucked in with the air remain in the water and are discharged from the machine body through an automatic drainage and discharge valve The dust particles sucked in with the air and impurities such as dust particles that fall off from the friction of moving parts are compressed together
Corrosive gas content The corrosive gases in the air are cleaned with pure water, left in the water, and discharged from the machine body through an automatic drainage valve The corrosive gases in the air are directly compressed and enter the machine, causing corrosion to the cast iron, ductile iron cylinders, and components of the piston compressor
Maintenance costs Low, taking the CHINAMFG with an installed power of 150kw as an example, the annual maintenance cost does not exceed ¥20000 Taking a piston engine with an installed power of 150kw as an example, the annual maintenance cost is around ¥100000
Maintenance consumables and accessories Water filter cartridge, air filter Oil coarse filter, oil fine filter, air valve, piston ring, support ring, oil scraper ring, packing, bearing shell, etc
Hygiene and cleanliness All components in contact with water and air are made of 304 or 316 food grade stainless steel, ensuring food grade safety, cleanliness, and hygiene. Most components in contact with water and air are made of ductile iron, cast iron, aluminum, or carbon steel, which are prone to corrosion, rust, and pollution of compressed air
Operating energy consumption and electricity bills The screw machine is a high-speed and light load machine, which saves about 20% energy compared to the piston machine when all new machines are used Low speed heavy load, high power consumption
Noise Low noise, taking the 242kw model as an example, the noise is around 80 decibels High noise, taking the 250kw model as an example, the noise is about 110 decibels
