APC by Schneider Electric ACF400 Rack Air Removal Unit for NetShelter SX 600mm
Overview
The APC by Schneider Electric ACF400 is a rack-mounted air removal unit engineered specifically for NetShelter SX 600mm enclosures, designed to extract heat-laden exhaust air from the top of the rack before it recirculates into cold aisles. In high-density server and network equipment deployments where passive airflow is insufficient, an active air removal unit like the ACF400 keeps inlet temperatures from climbing — protecting equipment and preserving thermal headroom without requiring a full row-level or room-level cooling redesign.
Universal voltage input at 100–240V, 50/60Hz means the ACF400 deploys across North American and international facilities without adapter hardware or separate SKUs for different power environments — a practical advantage when standardizing infrastructure across global sites.
Key Features
- NetShelter SX 600mm Form Factor: Engineered to mount in APC NetShelter SX 600mm-wide enclosures — no adapter brackets or custom fab required. If your environment uses 750mm NetShelter SX racks, verify the correct SKU before ordering.
- Universal 100–240V / 50/60Hz Input: Operates on any standard facility power feed worldwide, eliminating the need for stepdown transformers or region-specific units when deploying across multiple sites or internationally.
- Active Top-of-Rack Exhaust: Pulls hot exhaust air out of the rack plenum before it spills over into cold-aisle intakes — directly reduces the risk of thermal recirculation, which is the leading cause of inlet temperature rise in high-density cabinets.
Integration & Compatibility
The ACF400 is designed for the APC NetShelter SX 600mm rack family. Confirm rack width (600mm vs. 750mm) and available U-space before ordering. For deployments requiring row-level or in-row cooling rather than top-of-rack extraction, evaluate the broader APC by Schneider Electric thermal management line for the appropriate solution tier. This unit pairs naturally with rack cooling accessories such as blanking panels and airflow management kits to maximize containment efficiency.
Frequently Asked Questions
Q: Which rack enclosures is the ACF400 compatible with?
A: The ACF400 is designed for APC NetShelter SX 600mm-wide enclosures. It is not intended for 750mm NetShelter SX or other rack families without confirmed compatibility from APC documentation.
Q: What power input does the ACF400 require?
A: The ACF400 accepts universal 100–240V AC input at 50 or 60Hz, making it compatible with standard facility power in both North American and international environments.
Q: Does the ACF400 require a dedicated circuit?
A: Consult APC's installation documentation for current draw and circuit requirements specific to the ACF400. This information is not confirmed in the available product evidence and should be verified before electrical planning.
Q: Can the ACF400 be used with third-party racks?
A: The ACF400 is specified for APC NetShelter SX 600mm enclosures. Compatibility with third-party or non-APC racks is not confirmed by available evidence and should be validated with APC directly.
The ACF400 addresses a specific gap in top-of-rack thermal management for NetShelter SX 600mm enclosures — active exhaust extraction rather than relying on passive convection or room-level CRAC capacity alone. In practice, the universal 100–240V input means you can standardize on one SKU across domestic and international data hall deployments without separate procurement tracks.
Technical Highlights:
- NetShelter SX 600mm Fit: Purpose-built for APC's 600mm NetShelter SX family — no bracket adapters, no guesswork on mechanical fit. Wrong rack width (750mm) requires a different unit.
- Universal Voltage (100–240V / 50/60Hz): Single SKU covers global power environments, which simplifies sparing strategy and reduces procurement complexity for multi-site deployments.
- Active Hot-Air Extraction: Pulls exhaust air before it recirculates — the mechanism that directly reduces the inlet temperature delta in high-density cabinets where passive management is insufficient.
Deployment Considerations:
- Verify available U-space at the top of the target NetShelter SX enclosure before ordering — the ACF400 occupies rack units that competing equipment may already claim in a fully populated cabinet.
- Current draw and circuit loading data for the ACF400 are not published in the available evidence — confirm with APC's installation guide before committing to a panel/PDU configuration.
The ACF400 is most defensible in high-density NetShelter SX 600mm deployments — think telecom or edge compute closets running above 5–7 kW per rack — where top-of-rack exhaust extraction meaningfully reduces recirculation without a full in-row cooling retrofit.
