Stop sacrificing airflow control for energy efficiency. This unheated high-velocity air curtain delivers focused air separation and consistent performance for busy doorways, sustaining conditioned zones while minimizing infiltration and drafts. Operators benefit from durable, serviceable equipment designed for commercial settings that require reliable operation on 460 volts, 3-phase power.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe the air curtain housing weekly with a mild detergent and a soft cloth to remove grease and dust. Disinfect high-touch areas—control switches, mounting brackets, and adjacent door frames—using an EPA-registered sanitizer per label dwell time. Inspect and vacuum intake grilles monthly; remove debris to maintain airflow. Tighten mounting hardware and check electrical connections quarterly. Regular cleaning prevents cross-contamination, deters pests, and helps preserve finish and function.#@@#Additional Info#@#Mars Air Systems NH242-1UH-TS air curtain provides unheated, high-velocity airflow for 40"–47" openings, powered by a 1 HP motor at 460 volts, 60 Hz, 3-Ph.#@@#General Info#@#Description #@#
Stop sacrificing airflow control for energy efficiency. This unheated high-velocity air curtain delivers focused air separation and consistent performance for busy doorways, sustaining conditioned zones while minimizing infiltration and drafts. Operators benefit from durable, serviceable equipment designed for commercial settings that require reliable operation on 460 volts, 3-phase power.
#@@# Motor Power#@#
A single 1 HP motor provides the thrust needed for a 42-inch opening, enabling a concentrated high-velocity airstream that resists cross-traffic infiltration. Designers specified 1 HP to balance thrust and electrical load for common industrial supply circuits.
#@@# Electrical Compatibility#@#
Engineered for 460 volts at 60 hertz and 3-phase service, the unit integrates seamlessly with standard three-phase distributions in institutional and industrial facilities. Technicians can install it without step-up transformers in locations that already utilize 460v infrastructure.
#@@# Cabinet Construction#@#
Galvanized steel construction with a titanium silver powder coat finish resists corrosion and maintains appearance in high-traffic environments. Facility managers find the coated surface easier to clean and maintain, reducing lifecycle surface treatment costs.
#@@# Coverage Range#@#
Configured for door widths between 40 inches and 47 inches and effective up to an 8-foot opening height, the curtain matches common loading dock and service entrance dimensions. Planners can specify this model for moderate-height openings without oversizing or complex ductwork.
#@@# Serviceability#@#
A single-motor design simplifies access for maintenance and reduces downtime during routine service cycles. Technicians encounter fewer components, which shortens diagnostic time and minimizes replacement parts inventory.
#@@# Compliance Listing#@#
The unit carries an ETL sanitation listing, confirming third-party evaluation against established safety and sanitation standards.
#@@#Delivery Details#@#
• Please ensure to handle the product with utmost care.
• Check if the product you have received has all the essential parts and accessories.
• Make sure to examine the product for damage before signing the delivery receipt.
• Contact customer service for delivery concerns.
• Delivery times may vary based on location.#@@#deliverynotes#@#NA#@@#Maintenance Guide#@#Maintain the Mars Air Systems NH242-1UH-TS by scheduling coil and inlet grille cleaning every 30 days to sustain airflow and reduce motor load. Inspect mounting hardware and tighten fasteners quarterly. Lubricate motor bearings per manufacturer intervals and verify electrical connections at 460 volts, 3-Ph for corrosion or looseness. Replace worn impeller components and seals immediately. Test airflow uniformity after service to ensure proper door protection.
