  • Product Overview

    The Nilfisk AERO 31 INOX Wet/Dry Vacuum is a powerful yet easily maneuverable vacuum for indoor or outdoor use on various jobsites. Professionals enjoy the multiple upgrades—from automatic start/stop, an extra outlet for tools, and an easily-removable and heavy-duty stainless steel collection tank. It takes compact wet/dry vacuuming to a new level of productivity with a large, 30-liter (8 gallon) capacity and 127 maximum CFM. The Nilfisk Aero 31 is a robust and versatile machine for workers in automotive and construction industries.

    Nilfisk's Push & Clean feature also includes a semi-automatic filter cleaning system for quick and easy maintenance. For the highest level of filtration, consider the ALTO Aero 31 HEPA Wet/Dry Vacuum model, which includes a HEPA filter to remove 99.97% of dust and debris down to .3 microns.

    Multiple Design Upgrades

    • Compact, Lightweight Design: A lightweight canister design makes the Nilfisk ALTO AERO 31 a great option for cleaning wide open job sites as well as tight, difficult-to-reach spaces. It also allows for easy transport around your home or to various jobsites.
    • Stainless Steel Container: A heavy-duty, 8-gallon collection canister for durable and easy waste removal.
    • Built-in Storage: This vacuum includes a flat top for holding tools and built-in storage for the hose, power cord, and accessories.
    • Powerful yet Quiet Motor: A powerful motor has a 127 max CFM and an 84-inch water lift. Despite its power, this commercial vacuum has a maximum noise level of 64 decibels.
    • Additional Socket: Plug in small electric tools directly into this vacuum as you work, saving you time and important outlet space on jobsites and construction sites. This autostart outlet is ideal for small hand tools and allows you to turn the vacuum and tools on or off.
    • Push & Clean Filter Cleaning System: Working with fine dust can mean clogged filter cartridges. Nilfisk's Push & Clean system allows air to pass through the filter cartridge in the opposite direction to offer a gentle but effective filter cleaning. This semi-automatic system blasts dirt off the filter to easily restore high suction performance and increase productivity.

    Quality German Construction

    The Nilfisk ALTO AERO series is built with German-engineered technology to ensure the highest-quality clean and reliability. Nilfisk engineers used their deep customer understanding and technical expertise to make wet/dry clean-up low maintenance. Its easy-to-remove container makes disposing of waste a quick task, while its flat design was manufactured for tool storage during operation.

    In addition, the AERO series vacuums are fully sealed so there's no blow-through dust—making them ideal for lead paint, asbestos, and remediation work. Its quality construction also makes it a top choice for professionals in the automotive, building and construction, and multiple other industries. This Nilfisk AERO 31 INOX also includes a heavy-duty, easy-to-empty stainless steel collection container.

    Optional HEPA Upgrade

    The Nilfisk ALTO AERO 31 comes standard with a washable, efficient PET fleece filter and filter bag. This washable filter removes impurities down to 1 micron from your air. If you're looking for a superior filtration with HEPA certification, consider the Nilfisk AERO 31 HEPA model. This filtration catches 99.97% of all particles down to .3 microns. The available upgrade makes this model compliant with EPA RRP, OSHA, NIOSH, and DoD standards.
