Schulz 35 CFM Stand-Alone Dryer
Product overview: Schulz refrigerated air dryer rated at 35 CFM for use with 7.5 hp and 10 hp compressors. This model is a stand-alone dryer requiring one-micron filtration upstream for warranty compliance. It operates on 115V single-phase power, designed to remove moisture effectively before air enters downstream equipment. This option is ideal for shops needing a robust standalone solution with straightforward installation.
- Dryer only: kiosk-style single unit without additional filtration included
- Warranty considerations require pre-filtering to remove water and oil before the dryer
- Suitable for mid-range compressor capacities and durable for continuous use
Schulz 35 CFM With Pre-Filter
Product overview: This Schulz model combines 35 CFM cooling with an industrial water separator and coalescing filter to deliver moisture- and oil-free air. The kit is designed to provide a complete moisture management solution suitable for piping outside the dryer. It includes provisions to manage dew points and protect downstream equipment from oil carryover.
- Includes water separator and coalescing filter for oil removal
- Non-cycling refrigeration with 100 PSI operation
- Maximum inlet pressure up to 200 PSI; caution to avoid exceeding limits
Schulz 50 CFM Stand-Alone Dryer
Product overview: This 50 CFM Schultz dryer is optimized for larger systems with 10 hp and 15 hp compressor backing. It supports a 100 PSI to 200 PSI range with a dew point target around 41 degrees. The unit emphasizes a durable construction and compatibility with standard piping, making it a solid choice for mid-to-large scale shops needing consistent dryness and oil removal capabilities.
- High-capacity drying suitable for bigger compressors
- Pre-filter options help extend filter life and maintain performance
- Durable build suitable for industrial environments
Schulz 75 CFM With Regulator Pre-Filter
Product overview: This 75 CFM Schulz refrigerated air dryer comes as a complete kit with an industrial regulator, water separator, and an oil-removing coalescing filter. It is designed to deliver moisture-free, ultra-dry air and is configured to handle higher flow rates while maintaining stable pressure and dew point performance. Suitable for heavy-duty industrial use where consistent dryness is critical.
- Complete kit including regulator and filters
- High flow capacity with reliable dew point performance
- Intended for systems needing robust moisture and oil control
Ingersoll-Rand D72IN Refrigerated Dryer
Product overview: The D72IN refrigerated dryer emphasizes energy efficiency and reliability. It features efficient heat exchangers, a stainless steel demister, and a programmable electronic drain valve to minimize air loss and reduce energy consumption. The control system is designed for easy operation, with a microprocessor-based interface for adjusting system parameters and ensuring consistent dry air supply.
- Energy-efficient operation with robust moisture control
- Built-in reliability features including corrosion-resistant exchangers
- Smart controls for straightforward management
Buying Guide
Key considerations when selecting a refrigerated air dryer include capacity (CFM/SCFM) relative to your compressor size, dew point targets, and downstream filtration needs. Evaluate whether a stand-alone unit suffices or if a complete kit with water separators and oil-removing filters better protects your system. Consider the inlet pressure range, compatibility with your piping (NPT sizes), and maximum operating pressure to avoid damage to filters or the dryer itself. Energy efficiency, ease of maintenance, and the availability of spare parts are also important for long-term reliability.
When comparing models, factor in:
- Dryer capacity vs. actual compressor output
- Dew point performance and sensitivity to ambient conditions
- Pre-filter and post-filter options and compatibility with regulator kits
- Installation footprint and ease of integration with existing systems
- Manufacturer support and warranty coverage
