UF2 legacy ultrasonic fogger resource
The site distinguishes primary product information from copied legacy claims.
Use this reference map to understand which statements are current, archival, conflicting or dependent on the exact UF2 revision.
Primary legacy sources
Applied Physics UF2 and Utility Fogger material
- Applied Physics — Clean room foggers and DI Water Foggers. Source for nine transducers, level indicator, fill port, dual-speed fan, hose, power, dimensions, capacity, maintenance notes and the detailed 3 CFM / 60-minute table.
- Applied Physics — UF2 Video archive page. Source for the separate statement of about 4 CFM, 50 minutes and refillable extended operation.
- Applied Physics — Cleanroom and Utility fogger technology archive. Context for ultrasonic DI-water fog generation, localized applications and historical technology comparisons.
Current product sources
Applied Physics replacement categories
- CRF2-J Cleanroom Fogger — current nine-piezo, 0.26 m³/min, approximately 50-minute localized ultrasonic platform.
- CRF3 Cleanroom Fogger — current mid-volume ultrasonic platform.
- CRF6 Cleanroom Fogger — current higher-output dual-outlet ultrasonic platform.
- AP35 Ultrapure Cleanroom Fogger — current passive/dewar-style LN₂ platform.
Standards context
Technical references do not certify the equipment
- ISO 14644-3:2019 — test methods for cleanrooms and associated controlled environments.
- FDA aseptic-processing guidance — context for dynamic airflow visualization in aseptic processing.
- USP General Chapter <797> and USP General Chapter <800> — controlled-environment and hazardous-drug compounding context.
The standards govern facilities, processes, test methods and evidence. They do not transform a UF2 into a certified-compliant device by model name.
Claim tiers
How the site decides what wording to use
| Tier | Evidence | Site treatment |
|---|---|---|
| Current product truth | Active Applied Physics product information plus internal confirmation | Specific wording with a reminder to reconfirm before quotation/protocol use. |
| Primary legacy source | Applied Physics UF2 / Utility Fogger archive | Archival wording and revision qualifier. |
| Conflicting legacy source | Different values across AP pages | Range, conflict disclosure and no false precision. |
| Third-party copy | Distributor, reseller or translated legacy page | Corroborating lead only; not controlling. |
| Inference | Engineering interpretation from multiple facts | Clearly labeled recommendation, not stated as product history. |
Frequently asked questions
Practical answers
Why does the site not state a single UF2 CFM value?
Because the surviving Applied Physics pages conflict. The site preserves that evidence and uses a cautious range instead of manufacturing certainty.
Are the external standards reproduced here?
No. The site summarizes relevant context and links to authoritative sources. Users must obtain and follow the controlling version and facility procedure.
