The foundations of our company were laid by J\u00f3zsef Gyenese<\/b>, who tirelessly and enthusiastically always sought innovative technical solutions<\/span>. During his career, he served as chief engineer at the iconic R\u00e1ba factory in Gy\u0151r, technical director at the Rekard gear factory, and development project engineer at the Vienna University of Technology. He is credited with introducing bevel gear manufacturing at R\u00e1ba, developing gear and planetary gear systems, and introducing welding robots to Hungary through the IGM Rekard collaboration. From there, it was only a small step to screw compressor technology. The current owner and managing director of the company is Tam\u00e1s Gyenese. <\/span><\/p>\n\t\t\n\t<\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In Vienna, he met GardAustria, and together they founded Gard-Air Kft., which became the Hungarian representative of the global company Gardner Denver.<\/p>

During the period of regime change, they installed numerous Gardner Denver compressors for many large Hungarian companies, thereby establishing the brand’s strength in Hungary. His son and daughter joined the company after completing their university studies, and in 1998, concurrently with the establishment of the Budapest site, the company was reorganized and continued its work as DENV-AIR Kft., now with 100% family ownership. The current owner and managing director of the company is Tam\u00e1s Gyenese.<\/span><\/p>

As the brand representative for Gardner Denver, we have continuously provided sales and professional service tasks with nationwide coverage.<\/p>

Even in the 90s, Gardner Denver was committed to energy saving, and with Turn-Valve technology, we uniquely achieved 20-25% energy savings by opening windows beneath the screw rotors in the compression chamber during partial load, allowing less air to be compressed and recirculating the excess to the intake. This energy-conscious approach has remained a defining factor in the development of our new compressors ever since. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t <\/div>\n <\/div>\n <\/div>\n <\/section>\n \t\t

From the 2000s, we began building our own brand, first with the MODULO and ENERGY families, and then, in collaboration with another innovative Italian company, we introduced the DENV-AIR RVG, RVK, and RVD screw compressor families to the market. This was followed by the DENV-AIR MDVN and MDVS mobile compressor families, with which we successfully entered the Latin American market. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t <\/div>\n <\/div>\n

For our patent called L\u00c9G\u00c1GY (Air Bed), which was patented in most parts of the world, we developed a special small compressor and started its production at our Gy\u0151r site in 2005. With this compressor, the hardness of the bed can be adjusted according to users’ daily comfort needs, using a remote control while lying down. <\/p>

Due to increasing international trade demands, we sought new development opportunities. We worked extensively with Italian developers to understand and perfect inverter (variable speed drive) technology. We realized that only compressors designed from scratch to be compatible with this technology, featuring a special motor and drivetrain, could be the equipment of the future. Only then could the regulation be reduced from 100% to as low as 25%. The problem of motor cooling at low speeds became a significant development area, as did the design of bearings for inverter technologies. Based on practical experience, we have incorporated insulated bearings into the motors of our compressors. <\/p>

In addition to representing Gardner Denver, which is one of the world’s most significant compressor technology groups, encompassing hundreds of factories and brands (Wittig, CompAir, Elmo Richle, Tamrotor, Bottarini, GD, Champion\u2026), our company is also the importer of STANLEY piston compressors, the representative of the ROTAIR factory, a distributor and service provider for OMI, and the Western Hungarian representative for HONDA small machinery. Thanks to our nationwide service network, we also provide maintenance and service for these devices. For water treatment companies, we manufacture our uniquely developed DENV-AIR sewer cleaning equipment, which uses pulsating compressed air to clear blockages and deposits. Its basic supply is provided by a mobile compressor, and it is equipped with a complete filter line to ensure oil-free operation. Under the name DENV-AIR Limpia Playa, we have also developed sand cleaning equipment capable of cleaning polluted sections of white sandy beaches in the Caribbean. We are proud to say that in Cuba, not only our mobile and electric compressors are known, but almost every Gaviota luxury hotel is our partner, thanks to our professional HONDA gardening machines and sand cleaners. <\/p>

Based on our extensive experience in assembling unique tank-mounted compressors, we began developing our new compact screw compressor family.<\/p>

Based on our experience in compressor block refurbishment, we knew that the most ideal design would be one without V-belt or gear drives in the compressors. Manufacturers essentially overspeed the compressor blocks, allowing them to meet specific demands with a smaller block. However, this significantly reduces the lifespan of the block bearings. We wanted to move away from this outdated technology. We sought contact with pioneering developers in the market, and thanks to a state delegation, we established an innovative collaboration with one of our group’s suppliers. Our new partner was developing similar concepts, and we were able to join this activity in a timely manner. The results of our joint development were the prototypes that became the predecessors of our new DAAM and DAPM 100% direct-drive compressor family. Here, the motor rotor was mounted directly on the compressor block shaft, achieving ideal 100% direct drive, eliminating all transmission losses and potential failure points. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
