Product Specifications

Technical details and manufacturing context for Air Intake / Pump

Definition
The air intake/pump is a critical subsystem within air quality monitors that actively samples ambient air by creating negative pressure to draw air through intake ports into the analytical chamber. It ensures consistent airflow for accurate pollutant measurement and maintains proper sampling rates across varying environmental conditions. This component is designed for use in computer, electronic, and optical product manufacturing, specifically as a part of air quality monitoring systems. It operates through mechanical or pneumatic action to create suction, drawing ambient air through filtration elements into the monitoring system. The pump may use diaphragm, piston, or rotary mechanisms to generate controlled airflow with precise volume and velocity for reliable sampling. Key parameters include a flow rate of 1–5 L/min, vacuum pressure of -60 to -20 kPa, operating temperature range of -10 to 50°C, and storage temperature range of -20 to 70°C. It operates in non-condensing relative humidity of 0–95% RH and has an ingress protection rating of IP54–IP65 per IEC 60529. The pump requires a supply voltage of 12–24 V DC and consumes 1.5–6 W at nominal voltage. Noise level is 35–55 dB(A) at 1 m distance per ISO 3744. The component weighs 150–350 g including mounting bracket, with dimensions ranging from 60×40×30 mm to 80×50×40 mm. Materials on file include ABS plastic, stainless steel, silicone rubber, and a material grade of PPS+PTFE with UL 94 V-0 rating. Life expectancy is 10,000–20,000 hours of continuous operation at rated load. These values are directory reference ranges and must be confirmed for the specific model and application. Always verify model-specific values and standards with the legal manufacturer or supplier.
Working Principle
The air intake/pump operates by creating a negative pressure differential that draws ambient air through intake ports and filtration elements into the analytical chamber. This is achieved via mechanical or pneumatic action, such as a diaphragm, piston, or rotary mechanism. The pump generates controlled airflow with precise volume and velocity, ensuring consistent sampling rates for accurate pollutant measurement. The negative pressure is typically in the range of -60 to -20 kPa, and the flow rate is maintained at 1–5 L/min. The pump's operation is influenced by environmental conditions, such as temperature and humidity, which must be within specified ranges to prevent condensation or seal degradation. The pump is designed to operate continuously, with a life expectancy of 10,000–20,000 hours at rated load.
