Compressors are used to inject air into ponds or lakes through diffusers.

Pond aeration
Compressors are used to inject air into ponds or lakes through diffusers. Injecting compressed air into ponds or lakes will increase the oxygen content of the water, thereby preventing it from becoming polluted. Ventilation is also used to provide a suitable living environment for fish and other aquatic organisms, otherwise they will lack oxygen.
Air sampling
Air and dust sampling to determine the number and type of visible fungal colonies in blind spots of buildings, indicating the presence of severe fungal growth areas indoors ("amplifiers").
Gas analyzer
This instrument is used to check whether industrial chimney emissions contain hydrocarbons entering the atmosphere. The EPA regulates the levels of chemicals such as CO2, CO, SOX, and NOX in gases emitted into the atmosphere.
Gas detector
Portable flame ionization detector is used to measure the content of hydrocarbons in gas samples. Burning gas samples in an air hydrogen flame can detect the presence of hydrocarbons. When using an air hydrogen mixture for combustion, it results in a higher level of ionization, indicating the presence of hydrocarbons in the gas sample. The ionization level is directly proportional to the number of carbon atoms in the sample extracted by the diaphragm pump.
Leak detection
In many cases, it is necessary to use protective equipment to monitor and protect the fuel inside underground tanks. To prevent fuel leakage, use double walled oil tanks or plastic caps (applicable to old and single walled tanks). A vacuum is formed in the middle of the double walls, monitored by a pressure detector. The pump installed in the monitoring equipment constantly controls pressure changes and minimal leakage at pipe joints and threaded joints to a certain level. When the ultra-low pressure is reached, the pressure detector turns on the pump, and when the ultra-high pressure is reached, the pump is turned off.
Particle counter
For semiconductor, biotechnology product manufacturers, and pharmaceutical manufacturers, indoor air quality is crucial. At the aforementioned locations, the 'clean room' monitors the air for the presence of particles, dust, and pollutants. A particle counter is different from a gas analyzer in that it detects the size and quantity of pollutants and does not recognize the names of pollutants. Pass the sample through a laser beam, observe the scattering of the laser beam, and perform detection. This application not only requires easy control of flow, but also requires stable and non pulsating airflow.
Sewage aeration
This type of system is currently used to control wastewater in residential areas. Residential wastewater enters the sewage treatment tank, and the injected compressed air promotes the growth of aerobic microorganisms. Aerobic microorganisms convert organic matter in wastewater into gases and other microbial cell substances. In addition to oxygen supply, the aeration system also evenly mixes the substances in the aeration zone, providing super suitable conditions for microorganisms to be exposed to waste. Wastewater can be discharged into ditches or newly built or existing sewage treatment facilities permitted by local health regulations.
Oil and gas recovery
Oil and gas recovery refers to the process of sucking back the oil and gas released from the vehicle's fuel tank during refueling. Oil and gas recovery can prevent the reduction of ozone and the release of toxic pollutants in gasoline. The start and stop of the compressor rely on pressure sensors to detect pressure changes in the recovery tank. After oil and gas are sucked in, the liquid is sent into the liquid pipeline system or oil tank through oil and gas separation, and the gas is recovered in the recovery tank by the pump.
