ISO 14644 Cleanroom Particle & ACH Calculator

Size cleanroom HVAC air handling systems across ISO Class 1 through ISO Class 8 (Class 10 to Class 100,000 under FS 209E): calculate maximum allowable cumulative particle concentration limits ($C_n ext{ per m}^3$ across $0.1, 0.5, 1.0 ext{ and }5.0 ext{ }mu ext{m}$), determine required air change rates ($20 ext{ to }300 ext{ ACH}$), and cleanroom contracting profits.
