• Compact and portable
• Most cost-effective option
• Used as a pressure source in calibration and leakage tests, to draw gas samples into CO2 Indicator or smoke gage

The Model A-350 Aspirator Bulb can be used to source pressure for calibration and leak-checking tests. Simply squeeze the bulb after the tubing is connected to generate pressure. For applications such as our CO2 indicator, the aspirator bulb can be squeezed before inserting the tubing to draw a vacuum to pull the smoke or air from a duct or stack into the gage.
