Leak tester for aerosol valves
Ensure precision and reliability in aerosol valve functionality with advanced leak testing, designed to maintain quality standards and optimize your production line’s efficiency.

The LACTEST-4 from Marchesini Group is an automatic, continuous motion rotary machine engineered for inhaler leak testing. Specially designed for inhalers including MDIs, corticosteroid, and bronchodilator types, it ensures the integrity of each unit in the production line. Its robust steel frame houses precision mechanics, with a clear separation between transport and mechanical areas to adhere to cleanliness standards. The machine operates at speeds up to 250 inhalers per minute, optimizing your throughput efficiently. Equipped with two priming stations and a final control station, all functions are managed via a PLC with electronic speed control. Complying with cGMP norms, the LACTEST-4 offers height adjustments for valve pushers using a linear encoder, demonstrating excellent integration capabilities in pharmaceutical packaging lines. Additionally, its energy-efficient design and streamlined operation minimize downtime and maintenance, making it an ideal choice for inhaler manufacturers prioritizing product quality and regulatory compliance.
