This 12VDC mini diaphragm pump, with its -45 kPa pressure rating and 480 L/Hr flow or 8 lpm, suits olfactometer air delivery as a compact air compressor for precise odorant dilution and controlled airflow in entomology experiments like mosquito behavior studies.  Suitability for Olfactometers the pump generates negative pressure for pulling clean air through activated carbon filters, creating stable laminar flow (adjustable via needle valves) at 0.04-0.4 L/min per port. Its <65 dB noise ensures minimal interference during sensitive insect assays, while the 80g weight and 113x60mm size fit compact olfactometer manifolds. ​
