Knudsenpath

Pumpdown and conductance

Purpose-Built

A vacuum-system design studio for gas regimes, line conductance, effective pumping speed, pumpdown curves, gas loads, leaks, and chamber comparisons.

Core Features

Chamber-line-pump network builder
Molecular and viscous regime cues
Effective-speed and pumpdown curves
Gas-load and leak sensitivity
Unit-complete vacuum reference

Private by Design

No account, subscription, ads, tracking, third-party analytics, or developer-operated backend. Core features work offline, and your work stays on device unless you deliberately share or export it.

Use It Responsibly

Screening model. Validate pump curves, outgassing, seals, temperature, gas species and transitional-flow behavior for hardware decisions.
