Additional Information

Description

The Mars LoPro 2 Series is a commercial air curtain designed to separate indoor and outdoor environments across frequently used openings. The system directs a steady air column across the doorway, creating an invisible barrier that helps maintain indoor comfort while allowing people, carts, customers, and equipment to move freely.

LoPro 2 air curtains are well suited for applications where a compact profile, quiet operation, and dependable air separation are important. They support energy savings, indoor comfort, insect control, and environmental protection in commercial and light industrial facilities evaluating industrial HVAC air curtain solutions.

  • Slim, Low-Profile Design
    An 8″ low-profile cabinet supports commercial installations.
  • Variable-Speed Control
    Adjustable airflow allows the air column to be tuned to the application and doorway conditions.
  • Energy Savings
    Helps reduce heating and cooling losses by limiting the escape of conditioned air through open doors.
  • Insect & Airborne Contaminant Control
    Creates an air barrier that helps reduce the entry of flying insects, dust, fumes, and outdoor air.
  • Heated Options Available
    Supports applications requiring supplemental heated air at customer entrances or in occupied spaces.
  • Durable Commercial Construction
    Built for continuous use in commercial environments and active facility openings.

The LoPro 2 Series helps facilities maintain more stable indoor conditions while supporting HVAC efficiency, occupant comfort, and cleaner interior spaces. By reducing uncontrolled air exchange, the system can help lower HVAC strain and improve comfort near high-traffic entrances.

Its unobstructed design allows doors and entrances to remain accessible without slowing workflow or customer movement. For buildings also evaluating commercial and industrial air handling equipment, air curtains can support a broader strategy for airflow management and environmental control.

Frequently Asked Questions

The LoPro 2 Series is a low-profile commercial air curtain designed to create an air barrier across doorways and frequently used openings.

An air curtain directs a controlled stream of air across an opening to separate indoor and outdoor environments without blocking access.

Yes. By limiting conditioned air loss through open doors, the LoPro 2 Series can help reduce HVAC strain and support more efficient building operation.

LPV2 models are the standard LoPro 2 air curtains for commercial and light industrial applications. LPN2 models are ETL Sanitation Certified LoPro 2 units for foodservice and sanitation-sensitive environments.

Sizing depends on opening width, mounting height, traffic conditions, indoor conditions, and application goals. Lincoln Associates can help evaluate the right configuration.

Interested in a LoPro 2 Series?

Every Mars LoPro 2 Series installation begins with a review of the facility’s opening size, traffic patterns, environmental conditions, and comfort goals. Lincoln Associates provides product selection and technical guidance to help identify the right air curtain configuration for each project.

Tube Diameter

Use a caliper or tape measure to determine the outside diameter of the tubes.

If necessary, remove insulation to see the incoming and outgoing lines. Measure the diameter of the outside of the line to help determine connection size.

Standard connection types are MPT (male pipe thread), FPT (female pipe thread), and Copper Sweat Connection. MPT is threaded on the outside, FPT is threaded on the inside, and Copper Sweat is used for soldered connections

Fins per Inch

Using a ruler, count the number of fins on the coil within one inch. Normal fin counts will be between 4 and 14 FPI.

Fin Length

Measure in the direction of the tubes, regardless of which direction the tubes are running.

Fin Height

Measure in the direction of the fin.

Single, Double, and Half Serpentine

Rows are counted in the direction of airflow, no matter how the coil is installed. You can count rows by looking at either the header end or the return bend end of the coil. Note that headers or return bends may not be evenly spaced across the coil.

Fluid coils—hot water, chilled water, and glycol water—regulate building air temperature by heating or cooling air in Air Handling Units (AHUs). Constructed with multiple rows of tubes, typically copper, these coils efficiently transfer heat between air and circulating fluids. They are vital for year-round comfort, accommodating diverse fluids like glycols and thermal oils for varied HVAC needs.

Condenser coils transfer heat from refrigerant vapor to the outdoor air, ensuring efficient cooling in HVAC and refrigeration systems. Constructed from materials like copper or aluminum to maximize heat transfer, these coils are vital for maintaining precise temperature control in industrial and commercial environments.

Steam coils utilize the latent heat of steam, released during condensation from vapor to liquid. They feature efficient condensate management to prevent water buildup and ensure uniform steam distribution. Available in configurations for high and low-pressure applications, steam coils are highly effective for heating air in a wide range of environments.

Evaporator coils absorb heat from indoor air to cool and dehumidify spaces by evaporating refrigerant from liquid to vapor. Located indoors, these coils are essential for maintaining comfortable environments in industrial and commercial settings, offering excellent performance in cooling, process cooling, and dehumidification applications. They are versatile for use in Air Handling Units (AHUs), central systems, or duct installations.
