2-stage oil-free screw air compressor Gardner Denver EnviroAire T110 A350028047

Description 2-stage oil-free screw air compressor Gardner Denver EnviroAire T110 A350028047

In today's industrial world, where product quality and operational efficiency determine business competitiveness, choosing the right compressor equipment becomes a critically important decision. Gardner Denver's EnviroAire T/TVS 90-160 compressors with innovative 2-stage oil-free screw compression technology represent a new standard in clean compressed air production, combining Class 0 certified quality with unmatched energy efficiency.

These oil-free rotary screw compressors are designed for enterprises where even the slightest oil contamination of air can lead to catastrophic consequences: product spoilage, production shutdowns, brand reputation damage, and enormous financial losses. Pharmaceutical industry, food production, electronics industry, medical equipment manufacturing – all these sectors require absolutely clean air, and this is where EnviroAire compressors demonstrate their unique capabilities.

ISO 8573 Class 0 Certification: Absolute Air Purity

The Highest Quality Standard

EnviroAire T/TVS 90-160 compressors have TÜV certification according to ISO 8573 Class 0 standard – the most stringent class of compressed air quality in the world. This is not just a marketing claim, but an officially confirmed guarantee that the content of oil and oil vapors in the produced air is less than 0.01 mg/m³.

What Does Class 0 Certification Mean?

ISO 8573 classification defines compressed air purity levels according to three parameters: solid particles, water, and oil. Class 0 is the highest category, which goes beyond Class 1, guaranteeing that the air is practically perfectly clean. For comparison:

• Class 1: oil content < 0.01 mg/m³
• Class 0: technically zero oil content, confirmed by independent testing

Protection Against Critical Risks

Using compressors with Class 0 certification eliminates the following risks:

• Product spoilage due to oil contamination
• Quality standard violations in pharmaceutical and food industries
• Coating defects in automotive and electronics sectors
• Brand reputation damage due to quality issues
• Financial losses from product batch rejection
• Increased costs for air filtration and purification

Innovative 2-Stage Compression Technology

Optimized Screw Element Design

The heart of EnviroAire compressors is the optimized 2-stage oil-free screw element (airend), representing a revolutionary design that ensures maximum efficiency and reliability.

2-Stage Compression Operating Principle

Unlike single-stage compressors, where air is compressed in one pass, the 2-stage system works as follows:

1. First Stage: Air is drawn in and pre-compressed to intermediate pressure
2. Intercooling: Compressed air is cooled, increasing efficiency
3. Second Stage: Pre-compressed air reaches final operating pressure

Advantages of 2-Stage Design

• 14% higher energy efficiency compared to industry standard
• 9% greater productivity with the same energy consumption
• Up to 8% higher volumetric flow compared to competitors
• Lower compression temperature, extending component service life
• Reduced load on each stage, increasing reliability

Sealed Drive System

The 2-stage compression element is designed as a sealed, maintenance-free drive system. This means:

• No need for regular intervention in the mechanism
• Minimized contamination risk
• Increased operational reliability
• Reduced maintenance costs

UltraCoat™ Technology: Protection and Durability

Advanced Protective Coating

Gardner Denver applies exclusive UltraCoat™ technology – an advanced rotor and housing protection process that provides the strongest coating in the industry.

UltraCoat™ Characteristics

• Mechanical bonding: Coating is not just applied, but mechanically integrated with the surface
• Unmatched adhesive properties: Coating does not delaminate even under extreme loads
• High thermal resistance: Withstands temperature fluctuations without degradation
• Anti-corrosion protection: Prevents oxidation and surface corrosion

Stainless Steel Rotor

UltraCoat is applied in combination with a second-stage stainless steel rotor, creating a synergistic effect:

• Stainless steel provides natural corrosion resistance
• UltraCoat adds an additional protective layer
• The combination guarantees maximum durability
• Efficiency preservation throughout the entire service life

Protection Against Performance Degradation

Thanks to UltraCoat™, the rotor assembly maintains its geometric parameters for many years of operation, preventing:

• Volumetric flow reduction
• Pressure drop
• Increased energy consumption
• Premature wear
