About ewo

ewo - sustainable, precise and robust products

ince 1914, Hermann Holzapfel GmbH & Co KG in Stuttgart has been developing and manufacturing products in the fields of compressed air preparation, compressed air accessories, workshop air service, oxyfuel and propane welding technology.

Innovative thinking, top quality and an exceptional range of products, fast reaction times and continuous technical development have made ewo what it is today: a trademark for compressed air and oxyfuel fittings worldwide.

Our developments, based on customer-specific requirements in practice, especially in the field of compressed air preparation, document our competence also for individual solutions with a system. Our air service equipment of proven quality, reliability, operational safety and precision is appreciated by service stations and automotive workshops alike.

Our product range is divided into four major product groups or product areas, which are interrelated in many areas of application. There are also synergy effects in development and production, which we use in the interest of our customers.

Swabian thoroughness and perfection

Modern production and testing methods guarantee our consistently high quality standard. Added to this is the typical Swabian thoroughness coupled with the experience and inventiveness of our employees. A sophisticated system of control and measuring stations watches over the entire manufacturing process - this means that every part passes through several coordinated tests. The reliability and precision of our methods is proven by the fact that we are allowed to calibrate various measuring and testing devices for air technology in-house - in close cooperation with the calibration office.

Quality assurance

Performance data of our compressed air devices are determined and documented in extensive tests with the computer-aided test bench. The ongoing control of series production guarantees reproducible results.
