FAQ

Frequently Asked Questions

What is the Kashiyama NeoDry 7G?

The NeoDry 7G is the smallest oil-free dry vacuum pump in the Kashiyama NeoDry G-Series. It uses multi-stage Roots technology to deliver clean, oil-free vacuum in a compact, lightweight package, which makes it a fit for analytical instruments, laboratory systems, leak detection, mass spectrometry, and OEM equipment.

What are the pumping speed and ultimate pressure of the NeoDry 7G?

The NeoDry 7G provides 110 L/min of pumping speed and an ultimate pressure of 5.0 Pa. It runs on single-phase 100 to 240V auto-switching power and draws only 0.28 kW, so it fits compact, low-power installations.

Is the NeoDry 7G an oil-free vacuum pump?

Yes. The NeoDry 7G is a fully oil-free dry vacuum pump, so there is no oil in the vacuum path and no oil vapor backstreaming. It uses no PTFE tip seals, so it also avoids the particle contamination associated with scroll pumps, which suits sensitive analytical and clean-vacuum work.

Can the NeoDry 7G be used to back a turbo pump?

Yes. Its 110 L/min pumping speed and clean, oil-free operation make the 7G a common backing pump for turbomolecular pumps on mass spectrometers, electron microscopes, and analytical instruments. Confirm the required backing pressure for your turbo pump before finalizing the pairing.

How much moisture or water vapor can the NeoDry 7G handle?

With gas ballast, the NeoDry 7G handles up to 135 g/hr of moisture, which supports processes that produce water vapor or light condensables. For heavier vapor loads, a larger G-Series model may be a better fit, so share your process and we can help.

Does the NeoDry 7G need a nitrogen purge?

Standard NeoDry 7G operation does not require a nitrogen purge. The pump uses gas ballast to manage moisture in typical clean, dry applications. If your process involves high vapor loads or specialty gases, tell us and we will confirm the right purge or gas-ballast configuration.

How often does the NeoDry 7G need maintenance?

The NeoDry 7G is built for long service intervals, up to six years under clean, dry-gas operating conditions. Because it uses no tip seals, you avoid the seal wear, replacement cost, and downtime common with dry scroll pumps. Actual intervals depend on the application, so check current NeoDry documentation for your duty cycle.

How do I choose the right NeoDry model or request a quote?

Start with your required pumping speed, ultimate pressure, moisture load, and installation constraints. The 7G is the compact entry point at 110 L/min, and the 15G, 30G, and 36G step up in capacity. If you are unsure, request a quote or call 1-866-379-7867 and we will help you match a model to your application.
