SATOVAC OMT-D-1000 / CT-D-600 Oil Mist Collector

Overview

The SATOVAC CT-D-600 Oil Mist Collector is an engineered auxiliary device designed for integration with rotary vane and oil-sealed vacuum pumps operating in the rough vacuum range (atmospheric pressure down to 133.3 Pa). It functions on the principle of multi-stage mechanical coalescence and inertial impaction—capturing airborne oil aerosols generated during pump compression cycles before they exit the exhaust stream. Unlike passive mufflers or simple baffles, the CT-D-600 incorporates a replaceable, high-efficiency coalescing filter element housed within a stainless steel pressure-rated casing, enabling consistent separation efficiency across variable load conditions. Its primary engineering objective is dual-purpose: environmental containment of hydrocarbon-based pump oils (e.g., mineral, naphthenic, or synthetic ester oils) and acoustic attenuation of pulsating exhaust noise—both critical for laboratory, semiconductor tooling, and analytical instrument enclosures where ambient air quality and operational noise compliance are governed by ISO 14644-1 (cleanroom classification), OSHA 1910.1200 (hazard communication), and local occupational hygiene standards.

Key Features

• Stainless steel (SUS304) main housing with NPT or ISO-KF flange options for direct inline mounting on vacuum pump exhaust ports
• Coalescing filter media rated for ≥ 99.5% collection efficiency on oil droplets ≥ 0.3 µm per ISO 12103-1 (A4 test dust protocol adapted for lubricant aerosols)
• Maximum continuous operating pressure: 1.2 bar(g); compatible with pump exhaust backpressures up to 10 kPa without flow restriction
• Integrated silencing chamber with optimized baffle geometry—reduces broadband exhaust noise by 15–22 dB(A) depending on pump type and flow rate
• Filter service life indicator port (optional) and standardized 1/4″ NPT drain valve for condensed oil recovery
• CE-marked per EU Machinery Directive 2006/42/EC and compliant with RoHS 2011/65/EU for restricted substances

Sample Compatibility & Compliance

The CT-D-600 is validated for use with oil-lubricated rotary vane vacuum pumps having nominal pumping speeds ≤ 600 L/min at 50 Hz (e.g., models from Edwards, Pfeiffer, Leybold, and ULVAC). It accommodates standard pump oils including ISO VG 68 and VG 100 mineral oils, as well as PAO- and ester-based synthetic alternatives. The unit does not require electrical power or cooling water; operation is fully passive and maintenance-free between filter replacements. All wetted materials—including gaskets (FKM fluoroelastomer) and filter substrate—are chemically resistant to common vacuum pump oils and withstand intermittent exposure to water vapor and trace solvents. Documentation includes material declarations per REACH Annex XIV and full traceability of filter media batch certification per EN 1822-1:2022 (high-efficiency particulate air filtration standards).

Software & Data Management

As a purely mechanical, non-electronic device, the CT-D-600 does not incorporate embedded firmware, sensors, or digital interfaces. However, it supports integration into automated vacuum system monitoring frameworks via optional external pressure differential transducers (e.g., SATOVAC DP-100 series) mounted upstream/downstream of the unit. These analog 4–20 mA outputs can be logged in SCADA systems compliant with ISA-88/ISA-95 architectures or fed into LIMS platforms supporting ASTM E2500-23 (verification of ancillary equipment). Filter replacement intervals may be scheduled based on cumulative runtime or ΔP thresholds—fully auditable under GLP and GMP environments requiring 21 CFR Part 11–compliant electronic records when paired with validated data acquisition hardware.

Applications

• Protecting mass spectrometer inlet lines and turbomolecular pump forelines from oil backstreaming contamination
• Maintaining ISO Class 5–7 cleanroom air integrity in semiconductor photolithography tool clusters
• Reducing VOC emissions and improving indoor air quality (IAQ) in university physics and chemistry teaching labs
• Enabling compliance with local environmental permits for continuous vacuum operation in R&D facilities
• Extending service intervals of downstream dry pumps used in hybrid vacuum systems

FAQ

Is the CT-D-600 suitable for use with dry (oil-free) vacuum pumps?

No—it is specifically engineered for oil-sealed rotary vane pumps where oil mist generation is inherent to the compression mechanism.
What is the recommended filter replacement interval?

Under typical lab conditions (≤ 8 hrs/day, 50°C exhaust temp), replacement is advised every 6–12 months or when ΔP exceeds 3 kPa—verified using calibrated manometers.
Can the unit be installed vertically or horizontally?

Yes—orientation-independent design allows mounting in either configuration; however, vertical installation with drain valve at bottom is preferred for optimal oil recovery.
Does SATOVAC provide validation documentation for GMP environments?

Yes—upon request, IQ/OQ protocols, filter media CoA, and material compatibility reports are supplied in English for regulatory submission support.
