Accurate Thermal Systems ATS1026 Air Filter and Regulator

Overview

The Accurate Thermal Systems ATS1026 Air Filter and Regulator is an engineered pneumatic conditioning unit designed for precision laboratory and pilot-scale process applications—particularly those requiring clean, stable, and moisture- and oil-free compressed air supply. It operates on the principle of coalescing filtration combined with precision pressure regulation, delivering consistent inlet conditions to sensitive downstream equipment such as fluidized bed reactors, thermal analysis systems, gas chromatography sample introduction modules, and controlled-atmosphere gloveboxes. The unit integrates a 10 µm particulate filter, a coalescing separator for liquid aerosols (water and lubricating oil), and an adjustable diaphragm-type pressure regulator with integrated digital pressure display. This architecture ensures reliable air quality control while minimizing maintenance intervals and operational drift—critical for GLP-compliant thermal processing workflows.

Key Features

• Coalescing filtration stage removes airborne particles down to 10 µm and captures liquid aerosols—including condensed water vapor and compressor-derived oil mist—with >99.5% efficiency at rated flow.
• Automatic condensate drainage via gravity-fed sump with float-actuated drain valve; eliminates manual purging and prevents re-entrainment of trapped liquids into the airflow path.
• Digital pressure display (0–100 psi / 0–6.9 bar range) enables precise, real-time monitoring and repeatable setpoint adjustment of regulated outlet pressure—essential for fluidized bed fluidization velocity control and thermal stability in benchtop reactors.
• Integrated wall-mount bracket and standardized 3/8″ (9.5 mm) NPT outlet fitting allow rapid, leak-tight connection to fluidized bath manifolds or other pneumatic endpoints without adapter dependency.
• Constructed with corrosion-resistant aluminum housing and FDA-compliant elastomers (EPDM seals); compatible with ambient operating temperatures from 5°C to 45°C and inlet pressures up to 150 psi (10.3 bar).
• No external power required—the unit functions entirely pneumatically, supporting intrinsic safety requirements in Class I, Division 2 environments.

Sample Compatibility & Compliance

The ATS1026 is compatible with standard laboratory-grade compressed air sources (oil-lubricated or oil-free compressors) and nitrogen or synthetic air supply lines. Its filtration performance meets ISO 8573-1:2010 Class 4.3.3 for solid particle, water, and oil contamination when operated within specified flow rates (up to 40 SCFM / 1133 L/min). While not certified to ISO 13485 or FDA 21 CFR Part 11 (as it is a passive mechanical device), its design supports audit-ready documentation of air quality assurance in GMP-aligned thermal processing protocols—especially where fluidized bed drying, calcination, or catalyst activation require documented inlet air specifications per ASTM E2912 or USP .

Software & Data Management

The ATS1026 is a standalone hardware-only module with no embedded firmware, network interface, or software dependency. All operational parameters—including regulated pressure—are monitored locally via the integrated digital gauge, which provides analog-to-digital conversion with ±1% full-scale accuracy and 0.1 psi resolution. For laboratories implementing electronic lab notebooks (ELN) or LIMS integration, pressure setpoints and real-time readings may be manually logged or captured via optional third-party analog output modules (e.g., 4–20 mA transducer add-ons, sold separately). No audit trail, user authentication, or electronic record retention is provided—consistent with its classification as a Class I non-electronic ancillary device under ICH GCP and 21 CFR Part 11 definitions.

Applications

• Fluidized bed reactor inlet conditioning for nanoparticle synthesis, pharmaceutical granulation, and battery cathode precursor drying.
• Air supply polishing for thermogravimetric analyzers (TGA), differential scanning calorimeters (DSC), and dynamic vapor sorption (DVS) instruments requiring low-humidity carrier gas.
• Pneumatic actuation support in automated sample handling systems where pressure stability directly impacts valve timing reproducibility.
• Pre-regulation stage upstream of zero-air generators or catalytic scrubbers used in trace gas calibration setups.
• Field-deployable air preparation for mobile thermal testing labs conducting on-site material stability assessments per ICH Q1A(R3) guidelines.

FAQ

What is the maximum recommended flow rate for optimal filtration performance?
The ATS1026 achieves rated 10 µm particle removal and coalescing efficiency at flow rates ≤ 40 SCFM (1133 L/min); exceeding this may reduce residence time and compromise liquid separation.
Does the unit require periodic filter element replacement?
Yes—coalescing filter elements should be replaced every 6–12 months depending on inlet air quality and duty cycle; replacement kits (ATS-FIL-10M) are available through authorized distributors.
Can the digital pressure gauge be calibrated in-house?
The gauge is factory-calibrated and sealed; field recalibration is not supported. Users may verify accuracy against a NIST-traceable reference gauge using the test port located on the regulator body.
Is the ATS1026 suitable for use with corrosive gases such as HCl or Cl₂?
No—it is rated exclusively for compressed air, nitrogen, argon, and other inert, non-corrosive, non-reactive gases; exposure to acidic or oxidizing media will degrade internal seals and housing integrity.
What mounting options are included?
The unit ships with a pre-installed heavy-duty steel wall-mount bracket and hardware; panel-mounting adapters and DIN-rail kits are available as optional accessories.
