AIRSPADE

AIRSPADE is a brand of pneumatic excavation tools used to remove soil with a high-velocity air stream rather than mechanical digging. The product line is built around non-conductive barrels and non-sparking nozzles, which allow operators to work near energized electrical lines and in areas where flammable gases or dusts may be present. The tools are supplied as individual barrels, nozzle assemblies, and complete kits that include accessories such as dirt shields, extension sections, and hoses with universal couplers. Across the range, the common interface is a 3/4 in female NPT connection, and barrel length is typically 4 ft. Soil excavation rates vary by model, with published figures of 1.5 cfm, 1.8 cfm, and 2.3 cfm depending on the nozzle and configuration. These rates reflect the volume of soil that can be displaced per minute under specified air pressure and soil conditions, and they give maintenance and utility crews a way to match a tool to the expected digging rate and available compressor output. The non-conductive barrel construction is intended to reduce the risk of electrical conduction if the tool contacts a live conductor, while the non-sparking nozzle material is selected to lower the chance of ignition in explosive atmospheres. AIRSPADE tools are commonly used for safely exposing buried utilities before mechanical excavation, for root-zone work around trees, and for potholing in congested underground areas where hand digging is slow and mechanical digging is risky. 3G Electric supplies the AIRSPADE line as part of its industrial equipment catalog, offering individual barrels, nozzles, and kits with the accessory content noted in each listing. The catalog includes models such as ASU4150G4, ASA50105KT, HT106, ASU50150KT, ASU50225KT, ASU4150KT, HT107, and ASU4105KT, covering a range of excavation rates and kit configurations. For procurement and plant engineering teams, the relevant selection factors are the required soil excavation rate, the barrel length needed for the working depth, the connection size, and whether a kit with a dirt shield, extension, or hose is preferred over a bare tool. Because the tools are air-driven, they require a compatible compressor and air delivery system; the 3/4 in female NPT inlet is the standard connection point for the supply hose or coupler. 3G Electric provides these AIRSPADE products with the part numbers and specifications listed in the catalog, allowing buyers to cross-reference against existing equipment or specify replacements by MPN. The line is positioned for applications where excavation must proceed without metal-to-soil contact that could damage buried infrastructure or create a spark. This makes the tools relevant to electric utilities, gas distribution, water and wastewater, telecommunications, and tree care operations. The catalog entries include both tools with a single barrel and kits that add one or more accessories, so the buyer can choose the level of completeness needed for the job. All listings carry the manufacturer part number, the connection size, and the soil excavation rate where published, which supports direct comparison across models. 3G Electric ships AIRSPADE products globally and can quote individual items or kits based on the part numbers shown.

Frequently asked questions

Common questions about AIRSPADE from 3G Electric.

What is the difference between the AIRSPADE ASU4150G4 and the ASU4150KT?

The ASU4150G4 is a non-conductive barrel and non-sparking nozzle tool with a 4 ft barrel, 3/4 in female NPT connection, and a published soil excavation rate of 1.8 cfm. The ASU4150KT is a kit version that includes the same barrel and nozzle plus additional accessory content, such as a dirt shield or other items noted in the kit listing. Both share the same connection size and barrel length, so the choice depends on whether a bare tool or a kit with accessories is preferred for the job.

What soil excavation rates are available across the AIRSPADE tool range?

Published soil excavation rates in the AIRSPADE line include 1.5 cfm, 1.8 cfm, and 2.3 cfm. For example, the ASU4105KT kit is listed at 1.5 cfm, the ASU4150G4 and ASU4150KT are listed at 1.8 cfm, and the ASU50225KT kit is listed at 2.3 cfm. The rate depends on the nozzle and tool configuration. Actual performance will vary with air pressure, hose size, compressor output, and soil type, so the published figure should be used as a comparative reference rather than a guaranteed field result.

What connection size do AIRSPADE barrels and nozzles use?

The AIRSPADE tools listed in the 3G Electric catalog use a 3/4 in female NPT connection. This is the inlet where the air supply hose or coupler attaches. When specifying a replacement barrel or nozzle, confirm that the supply hose and fittings match this 3/4 in female NPT thread. The kits may include a hose with a universal coupler, as noted in the individual kit descriptions, which can simplify connection to existing air systems.

What accessories are included with AIRSPADE tool kits such as the HT106 or ASU50150KT?

Accessory content varies by kit. The HT106 kit includes a non-conductive barrel and non-sparking nozzle with a 4 ft barrel and 3/4 in female NPT connection. The ASU50150KT kit includes one extension with coupler. The ASU50225KT kit includes one hose with universal coupler. The ASA50105KT kit includes one dirt shield. Because kits differ in what they add, buyers should check the individual listing for the specific accessory set before ordering, especially when matching an existing tool set or standardizing across a crew.

Can AIRSPADE tools be used near live electrical lines?

AIRSPADE tools are built with non-conductive barrels and non-sparking nozzles, which are intended to reduce the risk of electrical conduction and spark generation when working near energized lines or in explosive environments. However, no tool eliminates all risk. Safe use depends on following the manufacturer's instructions, the site's electrical safety procedures, and any applicable regulations for working near live conductors. The non-conductive and non-sparking properties are design features, not a substitute for proper lockout/tagout, grounding, or other required safety measures.

What barrel length is standard for AIRSPADE air excavation tools?

The AIRSPADE tools in the 3G Electric catalog are listed with a 4 ft barrel length. This length is common across the models shown, including the ASU4150G4, ASU4150KT, HT106, HT107, ASU50150KT, ASU50225KT, and ASU4105KT. The 4 ft barrel allows the operator to work at a reasonable distance from the excavation point while maintaining control. If a different length is required, check the specific product listing or contact 3G Electric with the desired dimensions and part number.
