THB Heavy Duty Inline Particulate Filter With Metal Bowl
This inline particulate filter is designed for high-flow applications, featuring a 3/4″ NPT connection, a 140 CFM flow rate, and a 5-micron element to remove moisture and debris. The metal bowl includes a visible sight glass for easy monitoring, and a 250 PSI maximum input pressure with 215 PSI maximum output pressure. Wall-mounting hardware is included for convenient installation in compact spaces. Ideal as a first-line filter in shop air lines to extend the life of sensitive tools and equipment.
THB Heavy Duty Inline Compressed Air Pressure Regulator (3/4″ NPT, 140 CFM)
This regulator provides precise control from 7 to 215 PSI and supports a high flow rate of 140 CFM. It includes a wall-mount bracket and a gauge for easy pressure monitoring. The unit is rated for up to 215 PSI output and 250 PSI input, making it suitable for demanding shop environments where stable pressure delivery is essential for tools and spray equipment. The robust construction helps maintain consistent performance across varying loads.
THB Inline Pressure Regulator 7-215 PSI (3/4″ NPT, 175 CFM)
Another high-flow regulator option with the same 7–215 PSI adjustable range, but offering a higher 175 CFM flow rate. Includes wall-mount bracket and gauge. This model is ideal when a stable pressure is needed across multiple tools or when feeding high-demand equipment such as impact wrenches, nailers, or spray systems. The compact inline design simplifies integration into existing lines while maintaining robust performance under load fluctuations.
THB Industrial High Flow Particulate Filter With Metal Bowl (1″ NPT, 11oz)
This larger 1″ NPT filter handles higher-flow systems and includes a 5-micron element to remove most moisture and debris. The 11-ounce metal bowl with a protective cover provides ample capacity for continuous operation without frequent maintenance interruptions. It supports up to 225 PSI maximum input pressure and 215 PSI maximum output pressure, delivering reliable filtration for industrial air lines and heavier tools that demand steady air quality.
THB Edge Industrial In-Line Desiccant Air Dryer With Metal Bowl
This desiccant air dryer is designed to dry compressed air in-line, reducing moisture that can cause tool corrosion and performance issues. It features a metal bowl with a visible sight glass to monitor desiccant status and works best in combination with upstream moisture removal. The 3/4″ NPT connection makes it compatible with common shop air lines, offering a practical solution for pneumatic tools and delicate equipment sensitive to humidity.
Buying Guide
Inline air components influence reliability, maintenance, and overall performance. When selecting parts, consider:
- Application airflow and pressure: Choose regulators and filters that support your system’s maximum CFM and pressure. Regulators should cover your target operating range with a suitable safety margin.
- Filtration and moisture control: 5 micron filters handle debris and most moisture; pairing with a moisture-removal filter or desiccant dryer improves air quality for paint spraying or precision tools.
- Material and build: Metal bowls and rugged housings withstand industrial environments and reduce failure risk. Look for clear sight glasses for easy monitoring.
- Maintenance accessibility: Wall mounts and accessible bowls simplify draining and replacements, reducing downtime.
- Compatibility: Ensure thread size (3/4″ or 1″ NPT) matches your existing lines and that mounting hardware is included or readily available.
- Safety and pressure ratings: Check maximum input/output pressures and ensure all components are rated above your system’s operating pressure for safe operation.
Product selection depends on your specific needs: whether you prioritize filtration efficiency, higher airflow, or compact inline design. For mixed tool sets in a workshop, a combination of a high-flow particulate filter with a reliable regulator and a desiccant dryer provides balanced performance, moisture control, and stable pressure. For more sensitive pneumatic tools, consider upgrading to an inline filter with larger capacity and a desiccant dryer to minimize moisture-related issues.
