Venturi vacuum ejector Model 800008H E-Vac

single-stagefor cardboard boxesfor packaging

Overview
EXAIR In‑Line E‑Vac® low vacuum generators are compact, single‑stage vacuum units designed to deliver instantaneous vacuum at the point of use for porous materials (cardboard, textiles, delicate parts). Straight‑Through Mufflers are recommended where particulates are present and provide the best sound reduction (up to 26 dBA). Units are 6061 aluminum, mount directly to compressed air lines or with a clip, and require no electricity or moving parts.

Applications

• Pick & place of parts and equipment
• Bag and package opening
• Label placement and handling
• Vacuum forming and mold evacuation
• Vacuum filling and leak testing
• Container evacuation and vacuum packaging
• Clamping, chucking and robotic tooling
• Paper alignment and feed in printing equipment

Advantages

• Instantaneous vacuum at point of use
• Compact, lightweight and easy to mount
• No moving parts — minimal maintenance
• Quiet operation with muffler options
• Single‑stage design reduces vacuum fluctuation
• Durable 6061 aluminum construction
• Safe operation — no electricity required

Models (airflow & model numbers)
Available airflow sizes: 1.5, 2.1, 3.1, 5.4, 8.4, 12.6, 16.8 SCFM. Typical SKUs: 800001 → 800017. Examples: 1.5 SCFM = 800001 (800001M with Straight‑Through Muffler / P800001H shown on page for Standard Muffler). Replace 'M' with 'H' for Standard Muffler (closed end). Units deliver vacuum up to 21" Hg (71 kPa) and flows up to 18.5 SCFM (524 SLPM) for porous models.

Performance (summary)
Air consumption and typical sound levels vary by model. Example: 800005 consumes 5.4 SCFM; sound level with Straight‑Through Muffler ≈ 66 dBA; vacuum flow up to 5.59 SCFM at 0" Hg, decreasing with increasing vacuum. Higher models (800013, 800017) offer larger flows (up to 18.5 SCFM) with corresponding sound and vacuum characteristics.

Evacuation time (examples)
Example for 1 ft³ container: 800001 to 800017 show increasing speed with airflow. Sample times (to listed Hg) for 800005: 0"/3"/6"/9"/12"/15"/18"/21" = 0 / 0.80 / 2.00 / 3.50 / 5.65 / 8.70 / 15.65 / 39.90 seconds. See full model data for precise values.
