Closed-loop flow controller BAC 100i

for airmanualelectronic

Overview
Providing and documenting all critical parameters measured in delivered dose uniformity (DDU) and aerodynamic particle size distribution (APSD) testing of metered‑dose inhalers (MDIs), the Breath Actuation Controller model BAC 100i features an electronically‑operated timer‑controlled two‑way solenoid valve. Available with inlet/outlet reversed (BAC 100i‑R). The BAC 100i series uses the same flow meter, temperature and relative humidity connections and printing capabilities as the TPK 200iX/-R.

Applications
Designed for testing MDIs, DPIs, nebulisers, soft mist inhalers (SMIs) and nasal products to meet European and United States Pharmacopoeia requirements.

Key Features

• Suitable for DDU/APSD measurement of conventional and breath‑actuated MDIs
• User‑guided test setup for simplified workflow
• Automatic calculation of test duration from selected volume and flow rate
• Fully automated in‑situ impactor leak test with pass/fail indication
• Delay function for spacer/valved holding chamber (VHC) testing

Functional details
The BAC 100i includes an electronically operated timer and a fast‑acting two‑way solenoid valve for precise breath actuation control. Auto‑trigger options include an MDI actuation sensor and a footswitch. Temperature and relative humidity measurement capabilities are integrated.
