Mounting hardware is sold separately: JC-0960-096 — Angled "L" Bracket Kit, Set of 3 (for 72"-96" units), Anthracite Grey RAL 7016 — for wall or ceiling mounting JC-0963-72 — Concealed Wall-Mount Backplate Kit for 72" — for flush, low-profile installations JC-0964-KT — Right-Side Vertical Floor Mounting Kit, Anthracite Grey RAL 7016 — for vertical floor mounting beside the door (right side) JC-0965-KT — Left-Side Vertical Floor Mounting Kit, Anthracite Grey RAL 7016 — for vertical floor mounting beside the door (left side) JC-0966-KT — Heavy-Duty 3ft × 3ft Strut Bracket Kit, Set of 2 with Hardware — for industrial strut-based suspended installations Threaded Rod Ceiling Mount (no kit required) — built-in 3/8-16 threaded inserts on top of the unit accept field-supplied threaded rods and nuts. No more than 1-1/2″ of rod should protrude into the unit. For vertical floor-mount installations, specify the vertical kit (left or right) at time of order — vertical mounting requires factory configuration.

Basic Control Package (Included Standard): Auto On/Off via door switch (door switch sold separately) Enable/Disable dry contact for BMS or fire-relay integration Hand-Off-Auto (HOA) input (HOA switch sold separately) Advanced Control Package (Factory Upgrade): All features of Basic, plus: MODBUS BMS connectivity Built-in 20-second time delay for high-traffic doors Schwank.ONE remote monitoring & control connectivity Engineered for the Door The Epic12 is engineered for door openings between 3 and 14 feet wide, with recommended mounting height of 12 feet for climate separation or 10 feet for insect control. The USDA Mosquito and Fly Research Unit has confirmed that properly designed air curtains exclude 95–99% of flying insects. Schwank's complimentary Engineering Design Assistance includes load calculations based on your specific opening dimensions, climate, and door usage — ensuring proper velocity profiling (400–800 FPM at floor level across the full opening) for an optimal seal without discomfort to people passing through. Contact us for a free design consultation on your installation. Frequently Asked Questions How much energy can an Epic12 save? Air curtains can reduce energy loss at open doors by up to 30%, depending on traffic patterns, indoor/outdoor temperature differential, and total door-open time. Most installations deliver ROI within 1–3 years; high-utilization docks operating 20+ hours/day typically see payback in 6–12 months. Regional rebate programs (e.g. Enbridge in Ontario) can further accelerate payback — check with us for current rebate availability in your area. What door heights is the Epic12 designed for? The Epic12 is engineered for mounting heights of 10 to 14 feet, with 12 feet as the recommended installation height for optimal climate-separation performance. For pure insect-control applications, 10 feet is recommended. Is the Epic12 AMCA certified? Yes. The Epic12 is independently AMCA-certified for air performance per AMCA Publications 211 and 220 — covering airflow rate, average outlet velocity, outlet velocity uniformity, velocity projection, and power rating at free delivery. It also carries UL certification for North American electrical safety standards. Does the Epic12 require an external control box? No. The Epic12 features a factory-integrated control panel with single-point wiring entry. No external control box is required — a major installation advantage over competitive air curtains that ship with separate control boxes requiring additional wall space and conduit. What is the warranty? Ambient (unheated) models carry a 5-year limited warranty. Electric heated models carry a 2-year limited warranty. Warranty begins from date of shipment, applies to the original owner and subsequent transferees, and is conditional on installation per manufacturer specifications and applicable codes. What heated models are currently available? Electric heated 600V/3-phase models are currently shipping. 208V/3-phase and 480V/3-phase heated models are coming soon from Schwank — contact us to be notified when these configurations release, or to discuss current alternatives. All heated models require a wall-mounted disconnect switch sized per the unit's amperage and a thermostat (single- or two-stage depending on control package).
