HPDAVV 15KW 20HP Rotary Screw Air Compressor with Tank & Refrigerated Air Dryer
This HPDAVV compressor system delivers a powerful 20HP rotary screw air compressor combined with an 80-gallon ASME tank and an integrated refrigerated air dryer. It operates at 230 Volts and 3-phase 60Hz power, handling up to 125 PSI max pressure with an air flow of 81 CFM. The spin-on air oil separator is designed for quick, easy maintenance, effectively lowering oil content in compressed air while returning filtered oil to the compressor, optimizing performance and longevity.
Modular design enables accessible components for fast servicing, and routine upkeep requires only oil and filter changes at scheduled intervals. This industrial-grade system is built to provide reliable, dry compressed air for demanding environments.
SCHULZ 75 CFM Refrigerated Air Dryer with Regulator Pre-Filter
The SCHULZ 75 CFM air dryer is engineered for 15HP to 20HP compressors, featuring a non-cycling refrigerated system with a built-in industrial-grade air pressure regulator and water separator filter. Rated for up to 200 PSI with 1″ female NPT inlet and outlet, it ensures air dew points around 41 degrees, effectively removing moisture and oil remnants.
This complete kit includes moisture and oil removal filters vital for ultra-dry compressed air. It supports seamless installation with high durability, suitable for varied industrial and workshop applications.
SCHULZ 50 CFM Refrigerated Air Dryer for 10HP & 15HP Compressors
This stand-alone SCHULZ air dryer is suitable for smaller 7.5 to 15HP compressor setups, providing 50 CFM drying capacity at 115V single-phase power. It is critical to use a minimum 1-micron pre-filter for water and oil removal before air enters the dryer to maintain warranty and performance.
The product offers options for kits including stage 1 water separators and stage 2 coalescing filters, optimizing moisture and oil elimination before the drying process.
3/4″ NPT Industrial 4 Stage Air Dryer Water Separator System
The CAtArt 4-stage air filtration system supports compressed air systems with 3/4″ NPT ports and a 1/4″ NPT pressure gauge. Designed for up to 240 PSI, this setup includes a 5-micron pre-filter to remove the majority of moisture and particles, followed by a coalescing filter with 0.01-micron elements to remove 99.9% of oil and water.
Its automatic drain and locking regulator ensure consistent performance and easy maintenance indicator systems signal when filter replacement is necessary, suitable for paint spray and plasma cutter air lines.
Ingersoll-Rand D12IN 7 SCFM Refrigerated Air Dryer
The Ingersoll-Rand D12IN unit offers 7 SCFM drying capacity with advanced features such as stainless steel demisters and corrosion-resistant heat exchangers. Its programmable electronic drain valve minimizes air loss while removing moisture efficiently for long-term dry air supply.
Smart microprocessor controls enhance user-friendly operation with adjustable system parameters, making it suitable for precision applications requiring minimal moisture content in compressed air.
Buying Guide for Screw Air Compressors with Dryers
When selecting the best screw air compressor with dryer, consider these key factors to ensure the system meets your operational requirements:
Air Flow Capacity
Measured in cubic feet per minute (CFM), the air flow capacity must match your tool or process needs. Higher CFM units suit heavy industrial applications, while smaller capacities are appropriate for light duty tasks.
Operating Pressure
Check the maximum working pressure (PSI) rating to meet your compressed air application specifications. Ensure the compressor and dryer can handle your system’s pressure demands to avoid inefficiency or damage.
Dryer Type and Efficiency
Refrigerated air dryers are common in screw compressor systems. They cool compressed air to condense moisture before filtration. Evaluate the dew point temperature ratings and filtering stages to guarantee adequate moisture and oil removal, essential for sensitive equipment and painting processes.
Power Supply Compatibility
Verify voltage and phase requirements (single-phase vs. three-phase) to ensure compatibility with your facility’s electrical system. Industrial screw compressors often require three-phase power for stable operation.
Maintenance and Serviceability
Look for units with accessible filters and oil separators, with clear maintenance schedules to minimize downtime. Systems with modular, spin-on components simplify filter and oil changes, reducing operational costs.
Additional Filters and Accessories
Some dryers require pre-filters or coalescing filters to protect the dryer and maximize air quality. Consider systems that include complete kits with necessary filters and regulators to streamline setup and performance.
Durability and Brand Reputation
Choose products from reputable brands known for reliable industrial air systems. Durable construction, corrosion-resistant components, and stable pressure regulation contribute to longevity and consistent performance.
Application Specific Needs
Industrial environments such as paint spraying, plasma cutting, or pneumatic tool operation have varying moisture sensitivity. Match the compressor-dryer system’s capabilities to the required dryness level and contaminant filtering for optimal results.
