A.I.S. Blowers, Airlocks, and Rotary Valves form the heartbeat of pneumatic conveying and dust-controlled bulk material handling systems. Designed for reliable airflow management and consistent material isolation, AIS components ensure powders and granules move exactly where intended—without pressure loss, leakage, or safety compromises.
These systems are critical in food & beverage, pharmaceutical, nutraceutical, chemical, plastics, battery materials, minerals, and industrial manufacturing environments.
The System Logic (Why These Three Matter Together)
Bulk handling systems don’t fail dramatically. They fail quietly—through air loss, pressure imbalance, and inconsistent feeding.
AIS designs blowers, airlocks, and rotary valves as coordinated system components, not disconnected parts:
• Blowers generate controlled airflow
• Rotary valves meter and isolate material
• Airlocks maintain pressure differentials
When engineered correctly, conveying becomes predictable, gentle, and energy-efficient. When it’s not, production turns into interpretive dance.
AIS Blowers
Reliable Airflow for Pneumatic Conveying & Process Venting
AIS supplies positive displacement blowers and airflow solutions sized specifically for your conveying distance, material density, and system pressure requirements.
Key features include:
• Pressure or vacuum conveying configurations
• Oil-free air options for sanitary applications
• Heavy-duty industrial construction
• Low pulsation for stable conveying
• Quiet operation with acoustic enclosures
• Energy-efficient designs
Blowers can be supplied as stand-alone units or fully skid-mounted with silencers, filters, relief valves, and controls—ready to drop into production without field improvisation.
AIS Rotary Valves
Accurate Metering & Pressure Isolation
Rotary valves (also known as rotary feeders) are the gatekeepers of bulk solids. AIS rotary valves are designed to discharge material while maintaining system pressure integrity.
Available configurations include:
• Drop-through or blow-through designs
• Cast iron or stainless-steel housings
• Open-end, closed-end, or adjustable rotors
• Tight-clearance options for fine powders
• Wear-resistant coatings for abrasive materials
These valves deliver consistent feed rates while preventing air leakage, pressure loss, and dust escape.
AIS Airlocks
Dust-Tight Isolation Between Process Zones
Airlocks are used where material must pass between zones of differing pressure—such as bins to pneumatic conveying lines or dust collectors to discharge points.
AIS airlocks feature:
• Precision-machined sealing surfaces
• Heavy-duty shafts and bearings
• Flexible or rigid tip options
• Sanitary designs for food & pharma
• Easy-access maintenance panels
The result is reliable isolation with minimal maintenance and long service life—even under continuous-duty operation.
Materials of Construction & Sanitary Options
AIS offers configurations to match application and compliance needs:
• Carbon steel for industrial applications
• 304 / 316 / 316L stainless steel for sanitary service
• FDA-compliant seals and elastomers
• Polished internal surfaces for hygienic environments
• CIP-compatible designs where required
These options make AIS components suitable for everything from flour and sugar to APIs and battery powders.
ATEX & NFPA Compliance for Hazardous Areas
For combustible dusts and hazardous materials, AIS offers solutions compliant with:
• ATEX (Zones 20, 21, and 22)
• NFPA (NFPA 652, 654, 61, 68, and 69 as applicable)
Safety features may include:
• Explosion-proof motors and gearboxes
• Grounding and bonding provisions
• Pressure-rated housings
• Spark-resistant construction
• Isolation compatibility with explosion protection systems
These designs reduce risk while maintaining system performance—no trade-offs, no shortcuts.
Typical Applications
AIS blowers, airlocks, and rotary valves are commonly used in:
• Pneumatic conveying systems
• Bag dump station discharge
• Silo and bin discharge
• Dust collector discharge
• Milling and sifting systems
• Packaging and filling lines
If air and solids interact in your process, these components are doing the heavy lifting behind the scenes.
Why AIS?
AIS doesn’t size components from a brochure table and hope for the best. Every blower, airlock, and rotary valve is selected based on material behavior, system pressure, conveying velocity, and safety requirements.
That’s how you get consistent flow, long equipment life, and operators who stop blaming “the system” for everything.
