Welch has introduced a range of quiet vacuum/pressure pumps designed for continuous operation. The 2415, 2420, 2425, 2430, 2440, 2460 and 2478 feature built-in sound insulation that ensures whisper-quiet operation.
The linear pumps feature no sliding parts, so no lubrication is necessary. Exhausted air is always clean and particle-free.
Economically priced, the pumps are ideal for applications such as environmental monitoring, air sampling and water aeration.
