Gardner Denver

Gardner Denver is a world leader in industrial compression technology with a product portfolio spanning rotary screw compressors, reciprocating compressors, industrial blowers, vacuum pumps, and compressed air systems. With over 160 years of innovation, Gardner Denver delivers reliable solutions for the most demanding industrial compressed air and gas transport requirements worldwide.

The core Gardner Denver range includes oil-injected and oil-free screw compressors (7 to 2,000 kW), reciprocating piston compressors for high-pressure applications (up to 350 bar), centrifugal and rotary screw blowers for air and gas transport, and industrial vacuum pumps based on liquid ring, rotary piston, and screw technology. The Wittig sliding vane vacuum pumps and Nash liquid ring vacuum pumps are industry standards in the chemical and paper industries.

Gardner Denver products stand out through longer MTBF (Mean Time Between Failures), low energy consumption, and minimal maintenance requirements. Many models are equipped with advanced control systems such as the Smart Gauge controller, which optimizes energy consumption, adapts the pressure profile to actual demand, and signals predictive maintenance needs.

All Gardner Denver compressed air compressors are available in ATEX-certified versions for use in explosive atmospheres. Oil-free models (ISO 8573-1 Class 0) are essential in applications where air quality is critical, such as pharmaceutical production, food processing, and electronics manufacturing.

At Verkopershulp.nl we carry over 10,378 genuine Gardner Denver parts, including pressure valves, filters, oil separators, screw rotors, seals, and electronic control modules. As an authorized distributor we guarantee fast delivery, technical support, and full warranty on all parts.

History

Gardner Denver was founded in 1859 by Robert Gardner in Quincy, Illinois (USA) as a manufacturer of mining compressors and rock drills. In the early 20th century the company expanded its portfolio to industrial air compressors for various sectors. After decades of organic growth, strategic acquisitions followed of well-known brands including Nash (liquid ring pumps), Elmo Rietschle (vacuum technology), and Wittig (sliding vane pumps). In 2013 Gardner Denver was acquired by KKR & Co. and in 2017 listed on the NYSE. In 2019 Gardner Denver merged with Ingersoll-Rand's industrial activities to form Ingersoll Rand Inc., although the Gardner Denver brand name was retained for the industrial compression segment. Today Gardner Denver has manufacturing plants on four continents and distributes its products in more than 100 countries. The company invests heavily in energy-saving compressor technology, digital monitoring, and IoT-connected systems for predictive maintenance and efficiency management.

Frequently Asked Questions

What is the difference between an oil-injected and an oil-free Gardner Denver compressor?
Oil-injected compressors inject oil into the compression chamber for lubrication, cooling, and sealing. They are more energy-efficient but produce compressed air with traces of oil (max. Class 1-2 per ISO 8573-1). Oil-free compressors have no oil in the compression chamber and produce ISO 8573-1 Class 0 air, mandatory for pharmaceutical, food, and electronics applications.
Which Gardner Denver compressor parts are most critical for maintenance?
The most critical maintenance items are the air/oil filters, the oil separator (coalescing type), the inlet fan belt, the cooler element, and the screw rotors. Gardner Denver recommends replacing filters and the oil separator at every service interval. Verkopershulp.nl supplies genuine Gardner Denver service kits containing all required parts for a single maintenance service.
How often should I change the oil in my Gardner Denver compressor?
The oil change interval depends on the oil type used and operating conditions. For standard Gardner Denver compressor oil, the interval is typically 2,000 operating hours or annually, whichever comes first. With synthetic oil the interval can be extended to 4,000-8,000 hours. Always consult the maintenance manual for your specific model.
Are Gardner Denver parts suitable for use in ATEX zones?
Gardner Denver offers ATEX-certified versions of many compressors and blowers for use in zones 1, 2, 21, and 22 (gas and dust explosion risk). These models feature special motors, electrical components, and pressure safety systems complying with directive 2014/34/EU. Always verify the ATEX classification of the desired model with Verkopershulp.nl.
What does the Gardner Denver Smart Gauge controller do?
The Smart Gauge controller is the advanced control system in Gardner Denver compressors that monitors pressure, temperature, operating hours, and energy consumption. It regulates the pressure range for optimum energy efficiency, issues maintenance alerts based on operating hours, and provides diagnostic information during faults. External communication is available via Modbus, Profibus, or Ethernet.
How long do Gardner Denver screw rotors last?
Gardner Denver screw rotors are designed for a service life of 100,000 operating hours or more with correct maintenance. Wear is primarily determined by oil quality and filter cleanliness. Contaminated oil or excessively delayed oil changes are the most common causes of premature rotor wear.
Which Gardner Denver vacuum pump type is suitable for corrosive media?
Nash liquid ring vacuum pumps are particularly suited for corrosive, wet, or condensing gases thanks to their robust construction in stainless steel or special alloys. They have no mechanical friction seals in the gas path, minimizing wear from corrosive substances. Elmo Rietschle screw tandem pumps with PTFE coating are an alternative for dry corrosive applications.
How quickly are Gardner Denver parts delivered through Verkopershulp.nl?
Most common Gardner Denver replacement parts (filters, oil separators, valves, seals) are in stock and delivered within 1-3 working days. For less common or large parts such as rotors and heat exchangers, lead times are 5-15 working days depending on availability. Contact us for current stock information.
