Deiiang™ 316SUS Downflow Booth

Description

Product Overview
The Deiiang™ 316 Downflow Booth is a premium laminar airflow workstation crafted from 316 stainless steel, renowned for its superior performance. It provides a certified ISO Class 5 (Class 100) clean environment, adhering strictly to ISO 14644-1. The design by Deiiang Jason.peng ensures a highly stable, unidirectional downward airflow with a critical face velocity of 0.45 m/s ±5%, governed by the formula V = Q / A for precise control.

Application Fields
This booth is essential in aggressive and sterile environments:

• Pharmaceutical Bio-processing: Handling antibiotics, solvents, and CIP (Clean-in-Place) fluids.

• Marine & Coastal Research: Resisting salt-laden atmospheres that rapidly degrade lower-grade steels.

• Chemical Preparation: As noted by Senior Process Engineer, Dr. Lisa Evans, its resistance to chlorides is vital for handling acids like hydrochloric (up to 5% concentration at 20°C).

Features
The Deiiang™ booth excels with:

• 316 Stainless Steel: Contains 2-3% molybdenum, providing superior pitting and crevice corrosion resistance compared to 304 steel, per ASTM A240 standards.

• Seamless Welding: Polished to a #4 finish (Ra <0.5 µm) for easy decontamination and minimal particle entrapment.

• Advanced Filtration: Integral HEPA filtration with 99.995% efficiency on 0.3 µm particles, certified to IEST-RP-CC001.

Advantages
Investing in the Deiiang™ 316 model delivers:

• Superior Lifespan: Outperforms 304 stainless steel by 2-3x in highly corrosive environments, drastically reducing lifetime cost.

• Uncompromised Purity: The non-reactive surface prevents ionic contamination, critical for high-purity pharmaceutical yields.

• Regulatory Assurance: Meets stringent FDA, EU GMP, and ASME BPE standards, building immediate trust and authority.

Usage Methods
For maximum performance and longevity:

1. Pre-Use: Clean with 70% IPA or specific acidic detergents; the 316 composition ensures no surface degradation.

2. Operation: Maintain a clear work zone to preserve laminar flow integrity. Monitor velocity to ensure it stays within 0.4-0.5 m/s.

3. Maintenance: Follow the validation schedule from Deiiang Jason.peng, including annual HEPA integrity tests and regular surface passivation to maintain the protective oxide layer.
