A4 110V – a reliable solution for fast deployment
Designed for efficient drying, the new adsorption dehumidifier A4 110V combines compact design, powerful performance, and user-friendly features to meet the needs of professionals working in challenging environments.
Built for versatility and performance
The A4 110V is designed for both small and large dehumidification assignments and delivers consistent drying results across a wide temperature range – from heated environments to cold, unheated spaces. With a drying capacity of 17 liters/day and a nominal airflow of 250 m³/h, it’s ideal for construction sites, rental applications, and commercial projects.
Developed with the user in mind
Fast deployment and intuitive operation are enabled by easy-to-use analogue controls - making the machine suitable for everyone, from occasional users to professionals. The robust design is engineered for long service life, easy filter replacement, and efficient service and maintenance. Every detail is developed with the user in mind — from cord management with magnetic fastening to stackable construction for efficient logistics.
- 110 Volt version developed for commercial and construction sites.
- Low noise levels contribute to a better working environment.
- Compact and stackable design simplifies transport and storage.
- Ergonomic handle and slim design allow it to be carried close to the body, reducing strain on the back and greater compliance with safe handling requirements.
- Rounded, soft rubber corners enhance comfort when carrying the machine and help protect surrounding surfaces when moving through tight spaces.
